Measurement of differential top-quark-pair production cross sections in pp collisions at √s = 7TeV

S. Chatrchyan, +3867 more
TL;DR: Normalised differential top-quark pair production cross sections are measured in pp collisions at a centre-of-mass energy of 7 TeV at the LHC with the CMS detector using data recorded in 2011 corresponding to an integrated luminosity of 5.0 inverse femtobarns as discussed by the authors.
Journal ArticleDOI

Measurement of the muon charge asymmetry in inclusive pp →w+X production at s =7TeV and an improved determination of light parton distribution functions

S. Chatrchyan, +2197 more
- 13 Aug 2014 - 
TL;DR: In this article, the muon charge asymmetry in inclusive pp to WX production at 7 TeV was measured with a sample of more than twenty million W to mu nu events, and the statistical precision was greatly improved in comparison to previous measurements.
Journal ArticleDOI

Search for long-lived particles that decay into final states containing two electrons or two muons in proton-proton collisions at s =8TeV

Vardan Khachatryan, +2118 more
TL;DR: In this article, upper limits on the product of the cross section and branching fraction of such a signal are presented as a function of the long-lived particle's mean proper decay length.
