Abstract: We present the measurement of the B $^+$ meson production cross section with respect to the transverse momentum inclusively and, for the first time, in different charged particle multiplicities, in proton-lead collisions at a per nucleon center-of-mass energy of 8.16 TeV. The data were collected by the CMS detector during 2016 and correspond to an integrated luminosity of 175 nb $^{-1}$ . The measurement uses the exclusive decay channel $\mathrm{B}^{+}\!\to\! \mathrm{J}/\psi K^{+}$ . The inclusive results show a good agreement with the FONLL calculations.
