The polarization of the $\Lambda$ and $\overline{\Lambda}$ hyperons along the beam direction has been measured in proton-lead (pPb) collisions at a center-of-mass energy per nucleon pair of 8.16 TeV. The data were obtained with the CMS detector at the LHC and correspond …

The ratio between the prompt $\ensuremath{\psi}(2S)$ and $J/\ensuremath{\psi}$ yields, reconstructed via their decays into ${\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$, is measured in Pb-Pb and $p$-$p$ collisions at $\sqrt{{s}_{NN}}=2.76\text{ }\text{ }\mathrm{TeV}$. The analysis is based on Pb-Pb and $p$-$p$ data samples collected by CMS at the Large …
