The dependence of the ratio between the ${B}_{s}^{0}$ and ${B}^{+}$ hadron production fractions, ${f}_{s}/{f}_{u}$, on the transverse momentum (${p}_{T}$) and rapidity of the $B$ mesons is studied using the decay channels ${B}_{s}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\phi}$ and ${B}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{+}$. The analysis uses a data sample of proton-proton …

The structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, and polarization of the constituent partons. Such a structure can be studied using high-energy photons produced in ultraperipheral heavy-ion collisions. The first measurement of the azimuthal angular correlations …
