Performance of the CMS missing transverse momentum reconstruction in pp data at √s = 8 TeV

Vardan Khachatryan, +2191 more
- 12 Feb 2015 - 
TL;DR: In this paper, the performance of missing transverse energy reconstruction algorithms using 8 TeV proton-proton (pp) data collected with the CMS detector is studied. But the authors focus on the effects of large numbers of pileup interactions on the missing transversal energy resolution.
Journal ArticleDOI

Search for a charged Higgs boson in pp collisions at s√=8 TeV

Vardan Khachatryan, +2380 more
- 04 Nov 2015 - 
TL;DR: In this article, a search for a charged Higgs boson is performed with a data sample corresponding to an integrated luminosity of 19.7 +/- 0.5 fb(-1) collected with the CMS detector in proton-proton collisions at root s = 8,TeV.
Journal ArticleDOI

Observation of electroweak production of same-sign W boson pairs in the two jet and two same-sign lepton final state in proton-proton collisions at s√= 13 TeV

Albert M. Sirunyan, +2275 more
- 22 Feb 2018 - 
TL;DR: The first observation of electroweak production of same-sign W boson pairs in proton-proton collisions was reported in this article, where the data sample corresponds to an integrated luminosity of 359 fb^(−1) collected at a center-of-mass energy of 13 TeV with the CMS detector at the LHC Events are selected by requiring exactly two leptons (electrons or muons) of the same charge, moderate missing transverse momentum, and two jets with a large rapidity separation and a large dijet mass.
Journal ArticleDOI

Search for supersymmetry in hadronic final states using MT2 in pp collisions at √s = 7 TeV

S. Chatrchyan, +2174 more
- 02 Oct 2012 - 
TL;DR: In this paper, a search for supersymmetry or other new physics resulting in similar final states is presented using a data sample of 4.73 inverse femtobarns of pp collisions collected at sqrt(s)=7 TeV with the CMS detector at the LHC.
Journal ArticleDOI

Search for additional neutral MSSM Higgs bosons in the τ τ final state in proton-proton collisions at √s=13 TeV

Albert M. Sirunyan, +2390 more
- 17 Mar 2018 - 
TL;DR: In this paper, a search for additional neutral Higgs bosons in the τ τ final state in proton-proton collisions at the LHC was performed in the context of the minimal supersymmetric extension of the standard model (MSSM), using the data collected with the CMS detector in 2016 at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1.
