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.

- 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.

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

- 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.

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

S. Chatrchyan, +2255 more
- 20 Sep 2012 - 
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.

Measurement of electroweak production of two jets in association with a Z boson in proton–proton collisions at √s = 8 TeV

Vardan Khachatryan, +2141 more
TL;DR: The purely electroweak (EW) cross section for the production of two jets in association with a Z boson, in proton-proton collisions at √ s = 8 TeV, is measured using data recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 19.7 fb−1.
