Search for new physics in events with a leptonically decaying Z boson and a large transverse momentum imbalance in proton–proton collisions at √s = 13 TeV

Albert M. Sirunyan, +2257 more
- 11 Apr 2018 - 
TL;DR: In this article, a search for new physics in events with a Z boson produced in association with large missing transverse momentum at the LHC is presented, based on the 2016 data sample of proton-proton collisions recorded with the CMS experiment at s=13TeV, corresponding to an integrated luminosity of 35.9 fb-1.
Journal ArticleDOI

Search for a charged Higgs boson decaying to charm and bottom quarks in proton-proton collisions at √s=8 TeV

Albert M. Sirunyan, +2364 more
- 20 Aug 2018 - 
TL;DR: In this article, a search for a charged Higgs boson decaying to a charm and a bottom quark pair production was performed, where one top quark decays to a charged lepton, a neutrino, and a Bottom quark.
Journal ArticleDOI

Analysis of the CP structure of the Yukawa coupling between the Higgs boson and τ leptons in proton-proton collisions at $$ \sqrt{s} $$ = 13 TeV

Armen Tumasyan, +2283 more
- 01 Jun 2022 - 
TL;DR: The first measurement of the structure of the Yukawa coupling between the Higgs boson and τ leptons is presented in this paper , based on data collected in proton-proton collisions at the LHC.
Journal ArticleDOI

Measurements of tt¯ cross sections in association with b jets and inclusive jets and their ratio using dilepton final states in pp collisions at s=13TeV

Albert M. Sirunyan, +2202 more
- 10 Jan 2018 - 
TL;DR: In this paper, the cross sections for the production of tt-bar bb-bar and ttbar jj events and their ratio sigma[tt-bar bar]/sigma[t-Bar jj] were measured using data corresponding to an integrated luminosity of 2.3 inverse femtobarns collected in pp collisions at the LHC.
Journal ArticleDOI

Measurements of the associated production of a Z boson and b jets in pp collisions at s√=8TeV

Vardan Khachatryan, +2273 more
- 08 Nov 2017 - 
TL;DR: The production of a Z boson with at least two b jets is investigated, and differential cross sections are measured for the dijet system, and results are compared to theoretical predictions.
