Abstract

Measurements of the total and differential cross sections dσ/dp_T^B and dσ/dy^B for B^+ mesons produced in pp collisions at √s=7  TeV are presented. The data correspond to an integrated luminosity of 5.8  pb^(-1) collected by the CMS experiment operating at the LHC. The exclusive decay B^+→J/ψK^+, with J/ψ→μ^+μ^-, is used to detect B^+ mesons and to measure the production cross section as a function of p_T^B and y^B. The total cross section for p_T^B>5  GeV and |y^B|<2.4 is measured to be 28.1±2.4±2.0±3.1  μb, where the first uncertainty is statistical, the second is systematic, and the last is from the luminosity measurement.
