Measurements of production cross sections of WZ and same-sign WW boson pairs in association with two jets in proton-proton collisions at s=13TeV

Albert M. Sirunyan, +2395 more
- 10 Oct 2020 - 
TL;DR: In this paper, the first measurements of production cross sections of polarized same-sign W±W± boson pairs in proton-proton collisions are reported, based on a data sample collected with the CMS detector at the LHC at a center-of-mass energy of 13TeV, corresponding to an integrated luminosity of 137fb−1.

Search for pair produced fourth-generation up-type quarks in pp collisions at √s=7 TeV with a lepton in the final state

S. Chatrchyan, +2166 more
TL;DR: The results of a search for the pair production of a fourth-generation up-type quark (t′t′) in proton-proton collisions at View the MathML sources=7 TeV are presented, using data corresponding to an integrated luminosity of about 5.0 fb−1 collected by the Compact Muon Solenoid experiment at the LHC as discussed by the authors.
