Measurements of prompt ψ ( 2S ) meson production cross sections in proton–lead (pPb) and proton–proton (pp) collisions at a nucleon–nucleon center-of-mass energy of s NN = 5.02 TeV are reported. The results are based on pPb and pp data collected by …

Abstract A search is presented for the decays of heavy exotic long-lived particles (LLPs) that are produced in proton-proton collisions at a center-of-mass energy of 13 TeV at the CERN LHC and come to rest in the CMS detector. Their decays would …

The ${B}_{s}^{0}$ differential production cross section is measured as functions of the transverse momentum and rapidity in $pp$ collisions at $\sqrt{s}=7\text{ }\text{ }\mathrm{TeV}$, using the ${B}_{s}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}$ decay, and compared with predictions based on perturbative QCD calculations at next-to-leading order. The data sample, …
