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 …
