A kutatás összefoglalója, célkitűzései szakemberek számára
Itt írja le a kutatás fő célkitűzéseit a témában jártas szakember számára.
Az Európai Nukleáris Kutatási Szervezet (CERN) Nagy Hadronütköztetője (LHC) rekord 13 TeV tömegközéponti energiájú proton - proton ütközéseket szolgáltat, ezzel egy új energiatartományt nyitva meg a részecskefizikai vizsgálódások előtt. Kutatócsoportunk ezen világélvonalbeli kutatásokban vesz részt a Higgs-bozont 2012-ben felfedező CMS nemzetközi együttműködés tagjaként.

Célunk a CMS kísérlet adatainak segítségével a Standard Modell (SM) mögött megbújó alapvető elmélet vizsgálata, a SM kiterjesztései által jósolt új jelenségek kutatása két egymást kiegészítő módszerrel: az ismert SM folyamatok pontos mérésével illetve új részecskék közvetlen keresésével.

Az elektrogyenge szimmetriasértés vizsgálata különösen ígéretes út az Új Fizika felé. A két elektrogyenge vektorbozont tartalmazó végállapotok valamint a Higgs-szektor pontos mérésével és az elmélettel való összevetésével rávilágíthatunk a SM szükséges kiterjesztésésére, akár új rezonanciák megjelenésén, akár - ezek hiányában - a nagy energiájú viselkedés anomális mértékcsatolások okozta finom változásán keresztül.

A szuperszimmetria feltételezése az egyik legsikeresebb válasz a SM hiányosságaira, amely többek között egy megfelelő sötét anyag jelöltet is adhat. Csoportunk szuperszimmetrikus partnerrészecskék párkeltésének nyomai után is kutat, elsősorban top-kvarkokat vagy Higgs-bozont tartalmazó végállapotokban.

Fizikai céljaink megvalósításához elengedhetetlen résztvételünk az adatgyűjtésben, a berendezés működtetésében és folyamatos fejlesztésében, pontosságának mérésében. Javaslatunk így kiterjed hozzájárulásunkra a CMS belső nyomkövető detektorához és a luminozitásméréshez.

Mi a kutatás alapkérdése?
Ebben a részben írja le röviden, hogy mi a kutatás segítségével megválaszolni kívánt probléma, mi a kutatás kiinduló hipotézise, milyen kérdéseket válaszolnak meg a kísérletek.
A Standard Modell (SM) remekül leírja a laboratóriumban észlelt jelenségeket, ám számos kérdést hagy megválaszolatlanul. Mi a világegyetemet betöltő sötét anyag? Miért gyenge a gravitációs kölcsönhatás az ismert mértékkölcsönhatásokhoz képest? Megalkotható-e egy konzisztens elméletet, amely leírja mind a négy ismert kölcsönhatást? Ezek és hasonló kérdések arra utalnak, hogy a SM mögött egy ismeretlen Új Fizika rejtőzik.

A SM egyik legígéretesebb kiterjesztése a szuperszimmetria (SUSY) létezését posztulálja, amely a tér-idő legáltalánosabb, a fermionikus és bozonikus állapotok közti kapcsolatot megteremtő szimmetriája. Ennek következményeként minden ismert SM részecskének megjelenik egy szuperszimmetrikus párja. Ahhoz, hogy a szuperszimmetrikus kiterjesztés a hierarchia problémára megnyugtató választ adjon, a partnerrészecskék tömegének O(TeV) körül kell lennie, ami elérhetővé teszi keletkezésüket az LHC-n.

Ha az Új Fizika energiaskálája túl magasnak bizonyul új részecskék közvetlen keletkezéséhez, az LHC-n felfedezett Higgs-bozon tulajdonságainak, és az elektrogyenge vektorbozonok szórásának tanulmányozása ablakot nyithat a kiterjesztett elmélet felé. A két-bozon végállapotok pontos vizsgálata lehetőséget ad a magasabb skálájú fizikából származó anomális csatolások mérésére.

Célunk új részecskék közvetlen megfigyelése, amely egyértlemű jelét adná a SM-en túli fizika létének, illetve az anomális mértékcsatolások mérése, amely ennek hiányában információt szolgáltathat az alapvető elmélet tulajdonságairól. A differenciális hatáskeresztmetszet mérések azonban az Új Fizika jelenlététől függetlenül is fontosak a magasabb rendű perturbatív SM számolások ellenőrzéséhez.

Mi a kutatás jelentősége?
Röviden írja le, milyen új perspektívát nyitnak az alapkutatásban az elért eredmények, milyen társadalmi hasznosíthatóságnak teremtik meg a tudományos alapját. Mutassa be, hogy a megpályázott kutatási területen lévő hazai és a nemzetközi versenytársaihoz képest melyek az egyediségei és erősségei a pályázatának!
A protonok ütközéseinek vizsgálatával megérthetjük az elemi részecskék viselkedését kormányzó alapvető törvényeket és ezzel megérthetjük az Univerzum korai fejlődését, az Ősrobbanás utáni első mikromásodperceit.

Kutatásaink segítségével megválaszolhatjuk a részecske- és asztrofizika nyitott kérdéseit. Új (szuperszimmetrikus) részecskék felfedezése például lehetőséget adhat a Világegyetemet betöltő sötét anyag laboratóriumi tanulmányozására. A SM alternatív kiterjesztéseinek vizsgálatával, egyes modellek megerősítésével és mások kizárásásával közelebb juthatunk az alapvető elmélet megismeréséhez.

A technológiai újítások, amelyek a világélvonalbeli részecskefizikai kísérleti eszközök fejlesztésének velejárói a hétköznapi élet több területén is alkalmazásra találhatnak, ahogy ez a múltban is nem egyszer megtörtént.

A kísérletekbe rendszeresen bevonunk fiatal diákokat, a kutatócsoport tagjai részt vesznek a felsőoktatásban. Tudományterületünk művelésével, ismereteink, tapasztalataink, lelkesedésünk átadásával hozzájárulunk a fizika, természet- és mérnöki tudományok fejlesztéséhez és népszerűsítéséhez is.

A kutatás összefoglalója, célkitűzései laikusok számára
Ebben a fejezetben írja le a kutatás fő célkitűzéseit alapműveltséggel rendelkező laikusok számára. Ez az összefoglaló a döntéshozók, a média, illetve az érdeklődők tájékoztatása szempontjából különösen fontos az NKFI Hivatal számára.
Milyen törvények írják le a világunkat felépítő elemi részecskék viselkedését? Mi a Világegyetemünket betöltő sötét anyag? Vannak eddig felfedezetlen elemi részecskék, új kölcsönhatások, szimmetriák? Megalkotható a Mindenség Elmélete, amely közös alapokra helyezi az égi testek mozgását kormányzó gravitációt, az elektromos eszközeink működéséért felelős elektromosságot és a Nap energia termelését adó nukleáris kölcsönhatásokat?

Többek között ezeket a kérdéseket vizsgálhatjuk az Európai Nukleáris Kutatási Szervezet (CERN) Nagy Hadronütköztetője (LHC) mellett működő CMS kísérletben, ahol minden eddiginél nagyobb energiára gyorsított protonok ütközéseit vizsgálva a Világegyetem születése utáni néhány mikromásodpercben fennálló állapotokról is szerezhetünk új ismereteket.

Kutatócsoportunk célja az ismert részecskék tulajdonságainak tanulmányozásával és új, sosem látott jelenségek, részecskék felfedezésével hozzájárulni a mikrovilág és az Univerzum jobb megértéséhez.

angol összefoglaló

Summary of the research and its aims for experts
Describe the major aims of the research for experts.
The Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research provides proton-proton collisions at a record 13 TeV center-of-mass energy, opening a new energy regime for particle physics research. Our group participates in the world-leading CMS international collaboration that co-discovered the Higgs boson in 2012.

Our goal is to use the Run 2 CMS data to study the fundamental theory beyond the Standard Model (SM) by searching for new phenomena predicted by its various extensions with two complementary methods: the precise measurement of known SM processes and the direct search for new particles.

The study of electroweak symmetry breaking is a particularly promising way towards New Physics. The precise measurement of final states containing two electroweak vector bosons may shed light on the necessary extension of the SM, either through the appearance of new resonances, or, in their absence, through slight deviations in the high energy behavior from the theoretical predictions due to anomalous gauge couplings.

The postulation of supersymmetry is one of the best ideas to answer the deficiencies of the SM, among others it can provide a viable dark matter candidate. Our group will search for signs of pair production of supersymmetric partner particles, in particular in final states with top quarks or a Higgs boson.

To accomplish our physics goals, it is indispensable to participate in data taking, in the operation and improvement of the experimental apparatus and the measurement of its precision. Our proposal thus includes contributions to the inner tracking detector and the luminosity measurement.

What is the major research question?
Describe here briefly the problem to be solved by the research, the starting hypothesis, and the questions addressed by the experiments.
The Standard Model (SM) describes very precisely the phenomena observed in the laboratory, but leaves multiple questions unanswered. What is the dark matter that fills the Universe? Why is gravity weak compared to the other gauge interactions? Is it possible to construct a coherent theory that describes all four known interactions? These and similar questions indicate that an unknown New Physics hides beyond the SM.

One of the most promising extensions of the SM postulate the existence of supersymmetry (SUSY), the most general symmetry of space-time, linking fermionic and bosonic states. As a consequence, each SM particle gains a supersymmetric partner. Assuming that the extension provides a solution to the hierarchy problem, the partner particles are expected to have a mass in the order of TeV, which makes them susceptible to detection at the LHC.

If the energy scale of New Physics proves to be too high for the direct production of new particles, the study of the properties of the Higgs boson recently discovered at the LHC and of the scattering of electroweak vector bosons may open a window towards the extended theory. The precise study of two-boson final states allows the measurement of the anomalous couplings originating from higher-scale physics.

Our goal is the direct observation of new particles providing clear evidence of physics beyond the SM, and the measurement of anomalous couplings which - even if no new particle is seen - can provide information on the fundamental theory. The differential cross-section measurements, however, are important irrespective of the presence of New Physics to put higher order perturbative SM calculations to test.

What is the significance of the research?
Describe the new perspectives opened by the results achieved, including the scientific basics of potential societal applications. Please describe the unique strengths of your proposal in comparison to your domestic and international competitors in the given field.
Through the study of proton-proton collisions we can understand the fundamental laws governing the behavior of elementary particles, leading also to the understanding of the early Universe, the first microseconds after the Big Bang.

Our research can give answers to the open questions of particle and astrophysics. For example, the detection of new (supersymmetric) particles could allow the direct laboratory study of dark matter that fills our universe. With the study of alternative extensions of the SM, reinforcing some models and excluding others, we will get closer to the discovery of the fundamental theory.

The technological innovations that accompany the development of world-class particle physics experiments find use in multiple areas of everyday life, as it has happened many times in the past.

We often involve young students in the experiments, and the members of our research team participate in higher education. Through the cultivation of our fields of research, the transmission of our knowledge, experience and enthusiasm, we contribute to the development and popularization of physics, natural and engineering sciences.

Summary and aims of the research for the public
Describe here the major aims of the research for an audience with average background information. This summary is especially important for NRDI Office in order to inform decision-makers, media, and others.
What are the laws of nature that govern the behavior of the elementary particles that make up our world? What is the dark matter that fills our Universe? Are there undiscovered new particles, new interactions, new symmetries? Is it possible to construct the Theory of Everything that would describe in the same framework gravity that governs the movement of heavenly bodies, electricity responsible for the operation of our electrical appliances, and nuclear interactions that generate the energy in the Sun?

These are some of the questions that we study in the CMS experiment operating at the Large Hadron Collider (LHC) in the European Organization for Nuclear Research (CERN). By studying the collisions of protons accelerated to higher than ever energies we can also learn about the conditions in the first few microseconds after the birth of our Universe.

The goal of our research group is to contribute to the better understanding of the microscopic world and the Universe through the study of the properties of known particles and through the discovery of new phenomena and particles that were never seen before.

kutatási eredmények (magyarul)

Elektrogyenge vektorbozonpárok (VV') keletkezését, és két előre szórt nagy pszeudorapiditás különbségű hadronzáporral kísért (VV'jj) szórását tanulmányoztuk, valamint a Standard Model (SM) szuperszimmetrikus (SUSY) kiterjesztései által jósolt új nehéz részecskék megjelenését kerestük. A CERN LHC CMS kísérlet 13 TeV energián gyűjtött Run 2 adatkészletét dolgoztuk fel. Megfigyeltük Zγjj, Wγjj, WWjj elektrogyenge keletkezését 5σ feletti szignifikanciával, és bizonyítékot találtunk ZZjj keletkezésre 4σ szinten. A mért differenciális hatáskeresztmetszetek jó egyezést mutatnak a rendelkezésre álló magasabb rendű perturbatív QCD számításokkal, így szigorú felső korlátokat határoztunk meg az anomális csatolásokra egy 8 dimenziós effektív térelméletben, amely leírja az új fizika lehetséges hozzájárulását. A szuperszimmetrikus partnerrészecskék keresése R-paritás őrző modellekben nem hozott jelentős eseménytöbbletet a SM előrejelzéséhez képest, így a SUSY részecskepárok keletkezési hatáskeresztmetszetére és a partnerrészecskék (gluínók, skalár-t-kvarkok, csardzsínók és neutralínók) tömegére korlátokat adtunk meg különböző modellekben. Vezető szerepet vállaltunk a CMS detektor üzemeltetésében, kalibrálásában, teljesítményének mérésében és megújításában is, elsősorban a belső nyomkövető detektorra és a luminozitásdetektorokra koncentrálva. Precíziós luminozitás mérést végeztünk, amely elengedhetetlen a W-, Z- és Higgs-bozon, valamint a t-kvark folyamatok pontos méréséhez az LHC-n.

kutatási eredmények (angolul)

We studied electroweak (EW) vector boson pair (VV’) production, and vector boson scattering tagged by two forward jets with large rapidity separation (VV’jj), as well as searched for new heavy particles arising in supersymmetric (SUSY) extensions of the Standard Model (SM). We analyzed the Run 2 data set of the CMS experiment collected at 13 TeV energy at the CERN LHC. We observed EW production of Zγjj, Wγjj, WWjj with a significance above 5σ, and found evidence for ZZjj at the 4σ level. The measured differential cross sections show good agreement with the available higher order perturbative QCD calculations, and thus stringent upper limits were derived on anomalous couplings in a dim-8 effective field theory describing possible contributions from new physics. The searches for supersymmetric partner particles in R-parity conserving models did not reveal any significant excess over the SM predictions, and thus constraints on the production cross section of SUSY particle pair production, and on the mass of the partner particles (gluinos, scalar top quarks, charginos, and neutralinos) are presented in various SuGra and GGM models. We also co-led the operation, calibration, performance evaluation and upgrade efforts of the CMS detector, focusing on the inner tracking system and the luminometers. We performed precision luminosity determination which is essential for the accurate measurements of W, Z, and Higgs boson, as well as top quark processes at the LHC.
