A search for a narrow resonance with a mass between 350 and 700 GeV, and decaying into a pair of jets, is performed using proton-proton collision events containing at least three jets. The data sample corresponds to an integrated luminosity of 18.3 …

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 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 …
