dc.description.abstractMeasurements of the total and differential cross sections dσ/dpBT and dσ/dyB 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 pBT and yB. The total cross section for pBT>5  GeV and |yB|<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.es_ES
