A statistical combination of vector boson scattering measurements in proton-proton collisions at $ \sqrt{s} = $ 13 TeV is presented. The analysis is based on a dataset corresponding to an integrated luminosity of 138 fb$ ^{-1} $, collected with the CMS detector …

The influence of the initial-state geometry on the elliptic flow of prompt $ \mathrm{D^0} $ mesons in high-energy heavy ion collisions is explored. A lead-lead (PbPb) data sample at a center-of-mass energy per nucleon pair of 5.02 TeV and with an integrated …

Bound states of heavy quark-antiquark pairs, known as quarkonia, have long been regarded as particularly sensitive probes of the quark-gluon plasma (QGP). Comparing quarkonium yields in collisions of heavy nuclei, such as gold or lead, with a proton-proton (pp) reference reveals a …

The production of $ \tau $ lepton pairs via photon-photon fusion, $ \gamma\gamma \to \tau^{+}\tau^{-} $, is studied in ultraperipheral lead-lead collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The dataset, collected by the CMS experiment in 2018, corresponds to an …

Production of prompt P-wave charmonium states $ {\chi}_{c1} $(1P) and $ {\chi}_{c2} $(1P) is studied in proton-lead (pPb) collisions at a center-of-mass energy per nucleon pair of $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = $ 8.16 TeV. The analysis is based on data corresponding to an …

A study of the production of pairs of Z bosons (ZZ) and of the associated production of a Z boson and a Higgs boson (ZH) in final states containing two b quarks and two tau leptons ($ \mathrm{b}\mathrm{b}\tau\tau $) is presented. The …
