Measurements of the ${B}^{\rm +}$, ${B}^{\rm 0}$ and ${B}_{\rm s}^{\rm 0}$ production cross sections in pPb collisions at $\sqrt{s_{_{\text{NN}}}}$ = 5.02 TeV

Measurements of the differential cross sections $d\sigma^{\rm B}/dp_{\rm T}$ for $B^{\rm +}$, $B^{\rm 0}$ and $B_{\rm s}^{\rm 0}$ mesons in pPb collisions at $\sqrt{s_{_{\text{NN}}}}$ = 5.02 TeV are presented. The data correspond to an integrated luminosity of 34.8 ${\rm nb}^{\rm -1}$ collected by the CMS experiment at the LHC. The decay channels ${B}^{\rm +}\rightarrow~J/\psi~K^{\rm +}$, ${B}^{\rm 0}\rightarrow~J/\psi~K^{\rm *}(892)$ and ${B}_{\rm s}^{\rm 0}\rightarrow~J/\psi~\phi$ are used to detect B mesons and to measure their production cross sections. Nuclear modification factors, using FONLL calculations as a pp reference, at $\sqrt{s_{_{\text{NN}}}}$ = 5.02 TeV, are found to be equal to unity within experimental and theoretical uncertainties.
