Abstract The exclusive photoproduction of $$\mathrm {\Upsilon }\mathrm {(nS)} $$ Υ ( nS ) meson states from protons, $$\gamma \mathrm {p} \rightarrow \mathrm {\Upsilon }\mathrm {(nS)} \,\mathrm {p}$$ γ p → Υ ( nS ) p (with $$\mathrm {n}=1,2,3$$ n = 1 …

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 …
