Constraints on the χc1 versus χc2 Polarizations in Proton-Proton Collisions at s =8 TeV

Albert M. Sirunyan, +2298 more
- 24 Apr 2020 - 
TL;DR: In this paper, the polarizations of the produced chi(c1) and chi (c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at root s = 8 TeV.
Journal ArticleDOI

Measurement of differential $\mathrm{t\bar{t}}$ production cross sections using top quarks at large transverse momenta in $pp$ collisions at $\sqrt{s} =$ 13 TeV

Albert M. Sirunyan, +2377 more
- 01 Mar 2021 - 
TL;DR: In this article, a measurement of differential top quark pair (tt¯) production cross sections, where top quarks are produced at large transverse momenta, is reported, where the results are compared to various theoretical models.
Journal ArticleDOI

Search for a heavy resonance decaying to a top quark and a vector-like top quark in the lepton + jets final state in pp collisions at √ s=13TeV

Albert M. Sirunyan, +2262 more
- 07 Mar 2019 - 
TL;DR: In this article, a search was performed for a heavy spin-1 resonance decaying to a top quark and a vector-like quark partner in the lepton + jets final state.
Journal ArticleDOI

Studies of inclusive four-jet production with two b-tagged jets in proton-proton collisions at 7 TeV

Vardan Khachatryan, +2239 more
- 08 Dec 2016 - 
TL;DR: In this article, the authors measured the cross section for the production of at least four jets, of which at least two originate from b quarks, in proton-proton collisions.
Journal ArticleDOI

Search for CP violation in tt¯ production and decay in proton-proton collisions at √s=8 TeV

Vardan Khachatryan, +2340 more
- 20 Mar 2017 - 
TL;DR: In this paper, the results of a first search for CP violation in the production and decay of top quark-antiquark (tt) pairs are presented, based on asymmetries in Todd, triple-product correlation observables, where T is the time-reversal operator.
