A study of the production of prompt J / ψ mesons contained in jets in proton-proton collisions at s = 8 TeV is presented. The analysis is based on data corresponding to an integrated luminosity of 19.1 fb −1 collected with the …

Abstract Two related searches for phenomena beyond the standard model (BSM) are performed using events with hadronic jets and significant transverse momentum imbalance. The results are based on a sample of proton–proton collisions at a center-of-mass energy of $$13\,\text {Te}\text {V} $$ …

An analysis of the bottom baryon decay ${\mathrm{\ensuremath{\Lambda}}}_{b}\ensuremath{\rightarrow}J/\ensuremath{\psi}(\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}})\mathrm{\ensuremath{\Lambda}}(\ensuremath{\rightarrow}p{\ensuremath{\pi}}^{\ensuremath{-}})$ is performed to measure the ${\mathrm{\ensuremath{\Lambda}}}_{b}$ polarization and three angular parameters in data from $pp$ collisions at $\sqrt{s}=7$ and 8 TeV, collected by the CMS experiment at the Large Hadron Collider. The ${\mathrm{\ensuremath{\Lambda}}}_{b}$ polarization …

Abstract This paper presents combinations of inclusive and differential measurements of the charge asymmetry (A C) in top quark pair $$ \left(\mathrm{t}\overline{\mathrm{t}}\right) $$ t t ¯ events with a lepton+jets signature by the ATLAS and CMS Collaborations, using data from LHC proton-proton …

The first observation of top quark production in proton-nucleus collisions is reported using proton-lead data collected by the CMS experiment at the CERN LHC at a nucleon-nucleon center-of-mass energy of sqrt[s_{NN}]=8.16 TeV. The measurement is performed using events with exactly one isolated …
