Search for pair production of first-generation scalar leptoquarks at s =13 TeV

Albert M. Sirunyan, +2289 more
- 14 Mar 2019 - 
TL;DR: In this paper, a search for the pair production of first-generation scalar leptoquarks is performed using proton-proton collision data recorded at 13 TeV center-of-mass energy with the CMS detector at the LHC.
Journal ArticleDOI

Suppression of Excited gamma States Relative to the Ground State in Pb-Pb Collisions at root s(NN)=5.02 TeV

Albert M. Sirunyan, +2208 more
- 02 Apr 2018 - 
TL;DR: In this article, the yields of mesons produced in pp and Pb-Pb collisions at sNN=5.02 ǫTeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment.
Journal ArticleDOI

Search for exotic resonances decaying into WZ/ZZ in pp collisions at s√=7 TeV

S. Chatrchyan, +2267 more
- 07 Feb 2013 - 
TL;DR: In this article, a search for new exotic particles decaying to the VZ final state is performed, where V is either a W or a Z boson decaying into two overlapping jets and the Z decays into a pair of electrons, muons or neutrinos.
Journal ArticleDOI

Search for W' $\to $ tb decays in the lepton + jets final state in pp collisions at $\sqrt{s}$ = 8 TeV

S. Chatrchyan, +2252 more
- 23 May 2014 - 
TL;DR: In this paper, a search for the production of a heavy gauge boson decaying into a top and a bottom quark was conducted using a data set collected by the CMS experiment at sqrt(s) = 8 TeV and corresponding to an integrated luminosity of 19.5 inverse femtobarns.
Journal ArticleDOI

Search for heavy quarks decaying into a top quark and a W or Z boson using lepton + jets events in pp collisions at √s = 7 TeV

S. Chatrchyan, +2345 more
- 24 Jan 2013 - 
TL;DR: In this paper, a search for the pair-production of heavy quarks, Q Q-bar, that decay exclusively into a top quark and a W or Z boson was performed using a sample of proton-proton collisions at 7 TeV corresponding to an integrated luminosity of 5.0 inverse femtobarns, collected by the Compact Muon Solenoid experiment.
