Evidence for the direct decay of the 125 GeV Higgs boson to fermions

S. Chatrchyan, +2229 more
- 25 Jan 2014 - 
TL;DR: In this article, the authors reported strong evidence for the direct coupling of the 125 GeV Higgs boson to down-type fermions, with an observed significance of 3.8 standard deviations, when 4.4 are expected.
Journal ArticleDOI

Search for Dark Matter and Large Extra Dimensions in pp Collisions Yielding a Photon and Missing Transverse Energy

S. Chatrchyan, +2269 more
- 27 Jun 2012 - 
TL;DR: In this paper, a search for new physics in the final state containing a photon and missing transverse energy was conducted, and the authors set 90% confidence level (CL) upper limits for spin-dependent chi-nucleon scattering for chi masses between 1 and 100 GeV.
Journal ArticleDOI

Measurement of the inelastic proton-proton cross section at √s=13 TeV

Albert M. Sirunyan, +2343 more
- 07 Feb 2018 - 
TL;DR: A measurement of the inelastic proton-proton cross section with the CMS detector at a center-of-mass energy of $ \sqrt{s}=13 $ TeV is presented in this paper.
Journal ArticleDOI

Measurement of the differential and double-differential Drell-Yan cross sections in proton-proton collisions at s√ = 7 TeV

S. Chatrchyan, +2291 more
- 04 Dec 2013 - 
TL;DR: In this article, the Drell-Yan cross section was measured using an integrated luminosity of 4.5 (4.8) fb−1 in the dimuon (dielectron) channel of proton-proton collision data recorded with the CMS detector at the LHC at s√ = 7 TeV.
Journal ArticleDOI

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.
