Search for Narrow Resonances Decaying to Dijets in Proton-Proton Collisions at √[s]=13 TeV.

Vardan Khachatryan, +2252 more
- 18 Feb 2016 - 
TL;DR: In this article, a search for narrow resonances in proton-proton collisions at square root(s) = 13 TeV is presented, and the invariant mass distribution of the two leading jets is measured with the CMS detector using a data set corresponding to an integrated luminosity of 2.4 inverse femtobarns.
Journal ArticleDOI

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

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 massive resonances decaying into pairs of boosted bosons in semi-leptonic final states at s = 8 TeV

Vardan Khachatryan, +2189 more
- 29 Aug 2014 - 
TL;DR: In this article, a search for new resonances decaying to WW, ZZ, or WZ is presented, based on data corresponding to an integrated luminosity of 19.7 fb^(−1) recorded in proton-proton collisions at √s = 8 TeV.
