Study of $B$ Meson Production in $p+\mathrm{Pb}$ Collisions at $\sqrt{{s}_{NN}}=5.02\text{ }\text{ }\mathrm{TeV}$ Using Exclusive Hadronic Decays


CMS Collaboration; Khachatryan, V; Sirunyan, A M; Tumasyan, A; et al (2016). Study of $B$ Meson Production in $p+\mathrm{Pb}$ Collisions at $\sqrt{{s}_{NN}}=5.02\text{ }\text{ }\mathrm{TeV}$ Using Exclusive Hadronic Decays. Physical Review Letters, 116:032301.

Abstract

The production cross sections of the B$^+$, B$^0$, and B$_s^0$ mesons, and of their charge conjugates, are measured via exclusive hadronic decays in p+Pb collisions at the center-of-mass energy $\sqrt{^sNN}$=5.02  TeV with the CMS detector at the CERN LHC. The data set used for this analysis corresponds to an integrated luminosity of 34.6  nb$^{-1}$. The production cross sections are measured in the transverse momentum range between 10 and 60  GeV/c. No significant modification is observed compared to proton-proton perturbative QCD calculations scaled by the number of incoherent nucleon-nucleon collisions. These results provide a baseline for the study of in-medium b quark energy loss in Pb+Pb collisions.
