摘要：

This article summarizes the first measurements of inclusive beauty production cross section in proton-proton collisions at root s = 7 TeV and central rapidities. The results are based on different techniques, such as the identification of semileptonic b-decays into muons and inclusive jet measurements with secondary vertex tagging. The measurements probe b-quark production in different regions of transverse momenta. The experimental results are compared with next-to-leading order QCD predictions and various Monte Carlo models.
