Abstract Since the initial data taking of the CERN LHC, the CMS experiment has undergone substantial upgrades and improvements. This paper discusses the CMS detector as it is configured for the third data-taking period of the CERN LHC, Run 3, which started …

The second- and third-order azimuthal anisotropy Fourier harmonics of charged particles produced in $\text{pPb}$ collisions, at $\sqrt{{s}_{NN}}=8.16\phantom{\rule{0.16em}{0ex}}\text{TeV}$, are studied over a wide range of event multiplicities. Multiparticle correlations are used to isolate global properties stemming from the collision overlap geometry. The second-order …

Azimuthal correlations of charged particles in xenon-xenon collisions at a center-of-mass energy per nucleon pair of $\sqrt{{s}_{\mathrm{NN}}}=5.44$ TeV are studied. The data were collected by the CMS experiment at the LHC with a total integrated luminosity of $3.42\phantom{\rule{0.16em}{0ex}}\phantom{\rule{0.16em}{0ex}}\ensuremath{\mu}{\text{b}}^{\ensuremath{-}1}$. The collective motion of …

Measurements of azimuthal angular correlations are presented for high-multiplicity $p\mathrm{Pb}$ collisions at $\sqrt{{s}_{{}_{\mathrm{NN}}}}=5.02\phantom{\rule{0.16em}{0ex}}\text{TeV}$ and peripheral PbPb collisions at $\sqrt{{s}_{{}_{\mathrm{NN}}}}=2.76\phantom{\rule{0.16em}{0ex}}\text{TeV}$. The data used in this work were collected with the Compact Muon Solenoid (CMS) detector at the European Organization for Nuclear Research (CERN) …

Two-particle correlations in $p\mathrm{Pb}$ collisions at a nucleon-nucleon center-of-mass energy of $5.02\phantom{\rule{0.16em}{0ex}}\text{TeV}$ are studied as a function of the pseudorapidity separation ($\mathrm{\ensuremath{\Delta}}\ensuremath{\eta}$) of the particle pair at small relative azimuthal angle ($|\mathrm{\ensuremath{\Delta}}\ensuremath{\phi}|<\ensuremath{\pi}/3$). The correlations are decomposed into a jet component that dominates …

A search is presented for the production of two Higgs bosons in final states containing two photons and two bottom quarks. Both resonant and nonresonant hypotheses are investigated. The analyzed data correspond to an integrated luminosity of $19.7\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of proton-proton …
