Search for production of four top quarks in final states with same-sign or multiple leptons in proton-proton collisions at √{s }=13 TeV

Albert M. Sirunyan, +2295 more
- 31 Jan 2020 - 
TL;DR: The standard model (SM) production of four top quarks in proton-proton collisions is studied by the CMS Collaboration, with limits set on the production of a heavy scalar or pseudoscalar boson in Type-II two-Higgs-doublet and simplified dark matter models.
Journal ArticleDOI

Performance of the CMS Level-1 trigger in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2328 more
- 19 Oct 2020 - 
TL;DR: In this article, the authors describe the performance of the Level-1 trigger upgrade during the data taking period of 2016-2018, which implements pattern recognition and boosted decision tree regression techniques for muon reconstruction, including pileup subtraction for jets and energy sums, and incorporates pileupdependent isolation requirements for electrons and tau leptons.
Journal ArticleDOI

Evidence for Higgs boson decay to a pair of muons

Albert M. Sirunyan, +2451 more
- 25 Jan 2021 - 
TL;DR: In this paper, evidence for Higgs boson decay to a pair of muons was presented, which was performed using proton-proton collision data at 13 TeV, corresponding to an integrated luminosity of 137 fb$−1}, recorded by the CMS experiment at the CERN LHC.
Journal ArticleDOI

Searches for physics beyond the standard model with the MT2 variable in hadronic final states with and without disappearing tracks in proton-proton collisions at s=13Te

Albert M. Sirunyan, +2285 more
- 03 Jan 2020 - 
TL;DR: In this paper, two related searches for phenomena beyond the standard model (BSM) are performed using events with hadronic jets and significant transverse momentum imbalance, based on a sample of proton-proton collisions at a center-of-mass energy of $13,\text {Te}\text {V} $, collected by the CMS experiment at the LHC in 2016-2018 and corresponding to an integrated luminosity of 137$
Journal ArticleDOI

Search for nonresonant Higgs boson pair production in final states with two bottom quarks and two photons in proton-proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2417 more
- 29 Mar 2021 - 
TL;DR: In this paper, a search for nonresonant production of Higgs boson pairs via gluon-gluon and vector boson fusion processes in final states with two bottom quarks and two photons is presented.
