Inclusive b-jet production in pp collisions at sqrt(s)=7 TeV    [PDF]

CMS Collaboration

The inclusive b-jet production cross section in pp collisions at a
center-of-mass energy of 7 TeV is measured using data collected by the CMS
experiment at the LHC. The cross section is presented as a function of the jet
transverse momentum in the range 18 < pT < 200 GeV for several rapidity
intervals. The results are also given as the ratio of the b-jet production
cross section to the inclusive jet production cross section. The measurement is
performed with two different analyses, which differ in their trigger selection
and b-jet identification: a jet analysis that selects events with a b jet using
a sample corresponding to an integrated luminosity of 34 inverse picobarns, and
a muon analysis requiring a b jet with a muon based on an integrated luminosity
of 3 inverse picobarns. In both approaches the b jets are identified by
requiring a secondary vertex. The results from the two methods are in agreement
with each other and with next-to-leading order calculations, as well as with
predictions based on the PYTHIA event generator.
