Measurement of the differential Drell-Yan cross section in proton-proton collisions at s√ = 13 TeV

Albert M. Sirunyan, +2359 more
- 01 Dec 2019 - 
Abstract: Measurements of the differential cross section for the Drell-Yan process, based on proton-proton collision data at a centre-of-mass energy of 13 TeV, collected by the CMS experiment, are presented. The data correspond to an integrated luminosity of 2.8 (2.3) fb−1 in the dimuon (dielectron) channel. The total and fiducial cross section measurements are presented as a function of dilepton invariant mass in the range 15 to 3000 GeV, and compared with the perturbative predictions of the standard model. The measured differential cross sections are in good agreement with the theoretical calculations.

Search for single production of vector-like quarks decaying to a Z boson and a top or a bottom quark in proton-proton collisions at √s=13 TeV

Albert M. Sirunyan, +2316 more
- 25 Jan 2017 - 
TL;DR: In this paper, a search for single production of vector-like quarks, T and B, decaying into a Z boson and a top or bottom quark, respectively, was performed using data collected by the CMS experiment at the LHC in proton-proton collisions at 13 TeV, corresponding to an integrated luminosity of 2.3 inverse femtobarns.
