Open beauty measurements in pPb collisions with CMS

We report the first measurements of fully reconstructed B mesons in collisions involving heavy ions. Rapidity and transverse momentum cross sections, measured at $\sqrt{s_{NN}}=5.02$ TeV with the CMS detector, will be presented. For the same collision system, we will also report on the production of inclusive $b$-hadrons identified via their decays into $J/\psi$ displaced from the primary collision vertex, and measured in a similar kinematic range as the identified B mesons. The nuclear modification factors, which are constructed using a theoretically calculated pp reference, will be shown together with cross-section asymmetries between equivalent positive and negative pseudo-rapidity ranges in the center-of-mass frame of the collision.
