Measurement of the differential ?+2 b-jet cross section and the ratio ?(?+2 b-jets)/?(?+b-jet) in pp collisions at s = 1.96 TeV

Original language description

We present the first measurements of the differential cross section d?/dpT? for the production of an isolated photon in association with at least two b -quark jets. The measurements consider photons with rapidities |y?|<1.0 and transverse momenta 3015 GeV and |yjet|<1.5 . The ratio of differential production cross sections for ?+2 b -jets to ?+b -jet as a function of pT? is also presented. The results are based on the proton?antiproton collision data at s=1.96 TeV collected with the D0 detector at the Fermilab Tevatron Collider. The measured cross sections and their ratios are compared to the next-to-leading order perturbative QCD calculations as well as predictions based on the kT -factorization approach and those from the sherpa and pythia Monte Carlo event generators.
