Search for the standard model Higgs boson decaying into two photons in pp collisions at s=7TeV

S. Chatrchyan, +2250 more
TL;DR: In this article, a search for a Higgs boson decaying into two photons is described using a dataset recorded by the CMS experiment at the LHC from pp collisions at a centre-of-mass energy of 7 TeV, which corresponds to an integrated luminosity of 4.8 inverse femtobarns.
Journal ArticleDOI

Search for Signatures of Extra Dimensions in the Diphoton Mass Spectrum at the Large Hadron Collider

S. Chatrchyan, +2290 more
TL;DR: A search for signatures of extra spatial dimensions in the diphoton invariant-mass spectrum has been performed with the CMS detector at the LHC, and lower limits are set on the effective Planck scale in the range of 2.3-3.8 TeV at the 95% confidence level.
Journal ArticleDOI

Shape, transverse size, and charged-hadron multiplicity of jets in pp collisions at √s = 7 TeV

S. Chatrchyan, +2240 more
TL;DR: In this paper, the mean charged hadron multiplicity, the differential and integral jet shape distributions, and two independent moments of the shape distributions are measured as functions of the jet transverse momentum for jets reconstructed with the anti-kT algorithm.
Journal ArticleDOI

Measurement of the charge asymmetry in top-quark pair production in proton-proton collisions at s √ = 7 TeV

S. Chatrchyan, +2251 more
- 13 Mar 2012 - 
TL;DR: The difference in angular distributions between top quarks and antiquarks, commonly referred to as the charge asymmetry, is measured in pp collisions at the LHC with the CMS experiment.
Journal ArticleDOI

Exclusive γγ → +μμ - production in proton-proton collisions at √s = 7 TeV

S. Chatrchyan, +2289 more
TL;DR: In this article, a measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at 7 TeV, pp to p mu+ mu+ p, was reported using data corresponding to an integrated luminosity of 40 inverse picobarns.
