Measurements of the ϒ(1S) , ϒ(2S) , and ϒ(3S) differential cross sections in pp collisions at s=7TeV

Vardan Khachatryan, +2138 more
- 07 Oct 2015 - 
TL;DR: Differential cross sections as a function of transverse momentum are presented for the production of Y(nS) (n = 1, 2, 3) states decaying into a pair of muons in this article.
Journal ArticleDOI

Search for new physics with the M T2 variable in all-jets final states produced in pp collisions at √ s=13 TeV

Vardan Khachatryan, +2326 more
- 03 Oct 2016 - 
TL;DR: In this article, a search for new physics is performed using events that contain one or more jets, no isolated leptons, and a large transverse momentum imbalance, as measured through the MT2 variable, which is an extension of the transverse mass in events with two invisible particles.
Journal ArticleDOI

Search for Z′ resonances decaying to tt in dilepton+jets final states in pp collisions at √s=7 TeV

S. Chatrchyan, +2196 more
- 03 Apr 2013 - 
TL;DR: In this article, a search for resonances decaying to top quark-antiquark pairs is performed using a dilepton+jets data sample recorded by the CMS experiment at the LHC in pp collisions at √s=7 TeV corresponding to an integrated luminosity of 5.0
Journal ArticleDOI

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

Vardan Khachatryan, +2141 more
- 10 Feb 2015 - 
TL;DR: In this article, the electroweak cross section for the production of two jets in association with a Z boson, in proton-proton collisions at sqrt(s) = 8 TeV, is measured using data recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 19.7 inverse femtobarns.
Journal ArticleDOI

Measurements of $\mathrm{t\bar{t}}$H production and the CP structure of the Yukawa interaction between the Higgs boson and top quark in the diphoton decay channel

Albert M. Sirunyan, +2314 more
- 05 Aug 2020 - 
TL;DR: The first observation of the tt[over ¯]H process in a single Higgs boson decay channel with the full reconstruction of the final state (H→γγ) is presented, with a significance of 6.6 standard deviations (σ).
