Pseudorapidity distributions of charged hadrons in proton-lead collisions at √sNN=5.02 and 8.16 TeV

Albert M. Sirunyan, +2320 more
TL;DR: The pseudorapidity distribution of charged hadrons in proton-lead collisions at nucleon-nucleon center-of-mass energies root s(NN) = 502 and 816 TeV are presented in this paper.
Journal ArticleDOI

Development and validation of HERWIG 7 tunes from CMS underlying-event measurements

Rudolf Fruehwirth, +2494 more
TL;DR: New sets of parameters (“tunes”) for the underlying-event model of the HerWIG7 event generator are presented, and the tunes using a leading-order PDF for the simulation of MPI provide the best description of the data.
Proceedings Article

Search for a standard-model-like Higgs boson with a mass in the range 145 to 1000 GeV at the LHC

S. Chatrchyan, +2165 more
TL;DR: The combined upper limits at 95 % confidence level on products of the cross section and branching fractions exclude a standard-model-like Higgs boson in the range 145
Journal ArticleDOI

Study of the underlying event in top quark pair production in pp collisions at 13 TeV

Albert M. Sirunyan, +2257 more
TL;DR: In this article, normalized differential cross sections as functions of the multiplicity and kinematic variables of charged-particle tracks from the underlying event in top quark and antiquark pair production are presented.

Search for Neutral MSSM Higgs Bosons Decaying to μ⁺μ⁻ in pp Collisions at √s = 7 and 8 TeV

Vardan Khachatryan, +2294 more
