Inclusive and differential measurements of the tt charge asymmetry in pp collisions at √s=8 TeV

Vardan Khachatryan, +2297 more
- 10 Jun 2016 - 
TL;DR: In this article, the t t-bar charge asymmetry is measured in proton-proton collisions at a center-of-mass energy of 8 TeV, and the results are consistent within two standard deviations with zero asymmetry as well as with the predictions of the standard model.
Journal ArticleDOI

Measurement of the Lambda(b) polarization and angular parameters in Lambda(b) -> J/psi Lambda decays from pp collisions at root s=7 and 8 TeV

Albert M. Sirunyan, +2246 more
- 17 Apr 2018 - 
TL;DR: An analysis of the bottom baryon decay was performed to measure the Λb polarization and three angular parameters in data from pp collisions at s=7 and 8TeV, collected by the CMS experiment at the Large Hadron Collider.
Journal ArticleDOI

Search for top squark pair production in compressed-mass-spectrum scenarios in proton-proton collisions at s=8 TeV using the αT variable

Vardan Khachatryan, +2301 more
- 10 Apr 2017 - 
TL;DR: In this paper, an inclusive search is performed for supersymmetry in final states containing jets and an apparent imbalance in transverse momentum, p → T miss, due to the production of unobserved weakly interacting particles in pp collisions at a centre-of-mass energy of 8 TeV.

Measurement of the mass and width of the $W$ boson in $e^{+} e^{-}$ collisions at $\sqrt{s}$ = 189-GeV

P. Abreu, +495 more
- 05 Jul 2001 - 
TL;DR: In this paper, a measurement of the W mass and width has been performed by the DELPHI collaboration using the data collected during 1998 using the method of direct reconstruction of the mass of W from its decay products in both the W+W- -> lvqq and W+w- -> qqqq channels.

Search for resonant tt¯ production in lepton+jets events in pp collisions at s√=7 TeV

S. Chatrchyan, +2255 more
Abstract: A model-independent search for the production of heavy resonances decaying into top-antitop quark pairs is presented. The search is based on events containing one lepton (muon or electron) and at least two jets selected from data samples corresponding to an integrated luminosity of 4.4-5.0 fb^(−1) collected in pp collisions at s√=7 TeV. Results are presented from the combination of two dedicated searches optimized for boosted production and production at threshold. No excess of events is observed over the expected yield from the standard model processes. Topcolor Z′ bosons with narrow (wide) width are excluded at 95% confidence level for masses below 1.49 (2.04) TeV and an upper limit of 0.3 (1.3) pb or lower is set on the production cross section times branching fraction for resonance masses above 1 TeV. Kaluza-Klein excitations of a gluon with masses below 1.82 TeV (at 95% confidence level) in the Randall-Sundrum model are also excluded, and an upper limit of 0.7 pb or lower is set on the production cross section times branching fraction for resonance masses above 1 TeV.
