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 …

Abstract The average total energy as well as its hadronic and electromagnetic components are measured with the CMS detector at pseudorapidities $$-6.6<\eta <-5.2$$ -6.6<η<-5.2 in proton-proton collisions at a centre-of-mass energy $$\sqrt{s}=13\,\text {TeV} $$ s=13TeV . The results are presented as a …

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 …

Abstract Measurements of differential cross sections dσ/dϕ * and double-differential cross sections d2 σ/dϕ *d|y| for inclusive Z boson production are presented using the dielectron and dimuon final states. The kinematic observable ϕ * correlates with the dilepton transverse momentum but has …

For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from $\sqrt{{s}_{{}_{NN}}}=2.76\phantom{\rule{0.28em}{0ex}}\text{TeV}$ PbPb and $\sqrt{{s}_{{}_{NN}}}=5.02\phantom{\rule{0.28em}{0ex}}\text{TeV}$ $p\text{Pb}$ collisions collected by the CMS experiment at the …
