Abstract:

The production cross sections of

\mathrm{B}_{s}^{0}

mesons and charge conjugates are measured in pp and PbPb collisions via the exclusive decay channel

\mathrm{B}_{s}^{0}\to\mathrm{J}\hspace{-1pt}/\hspace{-1pt}\psi\hspace{2pt}\phi\to\mu^{+}\mu^{-}\mathrm{K}^{+}\mathrm{K}^{-}

at a center-of-mass energy

\sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} = 5.02\,\mathrm{Te\hspace{-1pt}V}

per nucleon pair and within the rapidity range (

|y|<2.4

) using the CMS detector at the LHC. The proton-proton (pp) measurement is performed as a function of transverse momentum of the

\mathrm{B}_{s}^{0}

meson in the range of 7 to 50

\hspace{2pt}\mathrm{Ge\hspace{-1pt}V}\hspace{-2pt}/\hspace{-1pt}c

and is compared to the predictions of next-to-leading order perturbative calculations.

\mathrm{B}_{s}^{0}

production yield in PbPb collisions is measured in two

p_{\mathrm{T}}

intervals, 7 to 15 and 15 to 50

\hspace{2pt}\mathrm{Ge\hspace{-1pt}V}\hspace{-2pt}/\hspace{-1pt}c

, and compared to the pp production yield in the same kinematic region. The nuclear modification factor, comparing

\mathrm{B}_{s}^{0}

meson yields in PbPb and pp collisions, was extracted and a comparison with the

\mathrm{B}^{+}

mesons was made. An indication of less suppression in production yield for

\mathrm{B}_{s}^{0}

mesons than for

\mathrm{B}^{+}

mesons in the PbPb system is seen but the difference is not significant within the current experimental uncertainties.
