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
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
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

Search for narrow and broad dijet resonances in proton-proton collisions at √s=13 TeV and constraints on dark matter mediators and other new particles

Albert M. Sirunyan, +2360 more
TL;DR: In this article, a low-mass search for resonances decaying into pairs of jets is performed using proton-proton collision data collected at s√=13 TeV corresponding to an integrated luminosity of up to 36 fb−1.
Journal ArticleDOI

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

Vardan Khachatryan, +2225 more
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

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.
