Journal ArticleDOI

Search for physics beyond the standard model in dilepton mass spectra in proton-proton collisions at √s=8 TeV

Vardan Khachatryan, +2198 more
- 07 Apr 2015 - 
TL;DR: In this article, the authors used a large extra dimensions model and a quark and lepton compositeness model with a left-left isoscalar contact interaction to search for both narrow resonances and broad deviations from standard model predictions.
Journal ArticleDOI

Centrality dependence of dihadron correlations and azimuthal anisotropy harmonics in PbPb collisions at √SNN = 2.76 Tev

S. Chatrchyan, +4138 more
- 01 May 2012 - 
TL;DR: In this article, measurements from the CMS experiment at the LHC of dihadron correlations for charged particles produced in PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV are presented.
Journal ArticleDOI

Charged particle multiplicities in pp interactions at sqrt(s) = 0.9, 2.36, and 7 TeV

Vardan Khachatryan, +2225 more
- 19 Jan 2011 - 
TL;DR: In this article, the multiplicity distribution of primary charged hadron multiplicity distributions for non-single-diffractive events in proton-proton collisions at center-of-mass energies of 0.9, 2.36, and 7 TeV, in five pseudorapidity ranges from |eta|<0.5 to |eta |<2.4.
Journal ArticleDOI

Search for diphoton resonances in the mass range from 150 to 850 GeV in pp collisions at $s =$ 8 TeV

Vardan Khachatryan, +2322 more
- 07 Jun 2015 - 
TL;DR: In this paper, a 19.7 inverse femtobarn sample of proton-proton collisions at 8 TeV was collected with the CMS detector at the CERN LHC.
Journal ArticleDOI

Missing transverse energy performance of the CMS detector

S. Chatrchyan, +2184 more
- 01 Sep 2011 - 
TL;DR: In this paper, the results of comprehensive studies of missing transverse energy as measured by the CMS detector are presented, and the results cover the measurements of the scale and resolution for missing transversal energy.
