Journal ArticleDOI

Search for electroweak production of charginos and neutralinos in multilepton final states in proton-proton collisions at √s=13 TeV

Albert M. Sirunyan, +2294 more
- 27 Mar 2018 - 
TL;DR: In this paper, a search for the direct electroweak production of charginos and neutralinos in signatures with either two or more leptons (electrons or muons) of the same electric charge, or with three or more hadronically decaying tau-leptons.
Journal ArticleDOI

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

S. Chatrchyan, +3867 more
- 19 Mar 2013 - 
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.
Journal ArticleDOI

Search for new physics in final states with an energetic jet or a hadronically decaying W or Z boson and transverse momentum imbalance at s =13 TeV

Albert M. Sirunyan, +2274 more
- 21 May 2018 - 
TL;DR: In this paper, a search for new physics using events containing an imbalance in transverse momentum and one or more energetic jets arising from initial-state radiation or the hadronic decay of W or Z bosons is presented.
