Search for excited leptons in proton-proton collisions at √s=8 TeV

Vardan Khachatryan, +2288 more
- 17 Mar 2016 - 
TL;DR: In this article, a search for compositeness of electrons and muons is presented using a data sample of proton-proton collisions at a center-of-mass energy of sqrt(s) = 8 TeV collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 19.7 inverse femtobarns.
Journal ArticleDOI

Search for R-parity violating supersymmetry with displaced vertices in proton-proton collisions at √s=8 TeV

Vardan Khachatryan, +2249 more
- 25 Jan 2017 - 
TL;DR: In this paper, the authors acknowledge the enduring support for the construction and operation of the LHC and the CMS detector provided by the following funding agencies: BMWFW and FWF (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN;

Measurement of the ratio of the 3-jet to 2-jet cross sections in pp collisions at s=7 TeV

S. Chatrchyan, +2158 more
- 26 Aug 2011 - 
TL;DR: A measurement of the ratio of the inclusive 3-jet to 2-jet cross sections as a function of the total jet transverse momentum in the range 0.2 0.5 TeV was proposed in this paper.
Journal ArticleDOI

Measurement of the production cross section of a W boson in association with two b jets in pp collisions at s?=8TeV

Vardan Khachatryan, +2245 more
- 11 Feb 2017 - 
TL;DR: The production cross section of a W boson in association with two b jets is measured using a sample of proton–proton collisions collected by the CMS experiment at the CERN LHC.
Journal ArticleDOI

Measurement of the cross section ratio σttbb/σttjj in pp collisions at √s = 8 TEV

Vardan Khachatryan, +2145 more
- 30 Jun 2015 - 
TL;DR: The first measurement of the cross section ratio σ_(ttbb)/σ_(ttjj) was presented using a data sample corresponding to an integrated luminosity of 19.6 fb^(−1) collected in pp collisions at √s = 8TeV with the CMS detector at the LHC as discussed by the authors.
