Abstract Jet production in lead-lead (PbPb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV is studied with the CMS detector at the LHC, using PbPb and pp data samples corresponding to integrated luminosities of 404 μb−1 and 27.4 …

The transverse momentum $({p}_{\mathrm{T}})$ distributions of $\mathrm{\ensuremath{\Lambda}}$, ${\mathrm{\ensuremath{\Xi}}}^{\ensuremath{-}}$, and ${\mathrm{\ensuremath{\Omega}}}^{\ensuremath{-}}$ baryons, their antiparticles, and ${K}_{S}^{0}$ mesons are measured in proton-proton $(pp)$ and proton-lead $(p\mathrm{Pb})$ collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV over a broad rapidity range. The data, corresponding to …

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 …

A bstract A measurement of the groomed jet mass in PbPb and pp collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV with the CMS detector at the LHC is presented. Jet grooming is a recursive procedure which sequentially removes soft constituents …

Charge-dependent azimuthal correlations of same- and opposite-sign pairs with respect to the second- and third-order event planes have been measured in $p\text{Pb}$ collisions at $\sqrt{{s}_{{}_{\mathrm{NN}}}}=8.16\phantom{\rule{0.28em}{0ex}}\text{TeV}$ and $\text{PbPb}$ collisions at 5.02 TeV with the CMS experiment at the LHC. The measurement is motivated …

The relative yields of $\mathrm{\ensuremath{\Upsilon}}$ mesons produced in $pp$ and Pb-Pb collisions at $\sqrt{{s}_{\mathrm{NN}}}=5.02\text{ }\text{ }\mathrm{TeV}$ and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are formed by comparing the yields of the …

The azimuthal anisotropy Fourier coefficients (v_{n}) in 8.16 TeV p+Pb data are extracted via long-range two-particle correlations as a function of the event multiplicity and compared to corresponding results in pp and PbPb collisions. Using a four-particle cumulant technique, v_{n} correlations are …
