Bound states of charm and anticharm quarks, known as charmonia, have a rich spectroscopic structure that can be used to probe the dynamics of hadron production in high-energy hadron collisions. Here, the cross section ratio of excited (ψ(2S)) and ground state (J/ψ) …

A search is presented for heavy bosons decaying to $Z(\ensuremath{\nu}\overline{\ensuremath{\nu}})V(q{\overline{q}}^{\ensuremath{'}})$, where $V$ can be a $W$ or a $Z$ boson. A sample of proton-proton collision data at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$ was collected by the CMS experiment during 2016--2018. The data correspond to …

A first observation is presented for the electroweak production of a W boson, a photon, and two jets in proton-proton collisions. The W boson decays are selected by requiring one identified electron or muon and an imbalance in transverse momentum. The two …

Abstract The ratios of the production cross sections between the excited ϒ(2S) and ϒ(3S) mesons and the ϒ(1S) ground state, detected via their decay into two muons, are studied as a function of the number of charged particles in the event. The …
