Measurement of the Z/γ*+b-jet cross section in pp collisions at √s = 7 TeV

S. Chatrchyan, +2320 more
- 01 Jan 2012 - 
TL;DR: In this article, the production of b jets in association with a Z/gamma* boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7TeV and recorded by the CMS detector.
Journal ArticleDOI

Non-Gaussian elliptic-flow fluctuations in PbPb collisions at root S-NN=5.02 TeV

Albert M. Sirunyan, +2301 more
- 10 Feb 2019 - 
TL;DR: In this article, an event-by-event fluctuations in the elliptic-flow coefficient v(2) are studied in PbPb collisions at root S-NN = 5.02 TeV using the CERN LHC.
Journal ArticleDOI

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

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.
