Measurement of differential cross sections of isolated-photon plus heavy-flavour jet production in pp collisions at √s =8 TeV using the ATLAS detector

Original language description

This Letter presents the measurement of differential cross sections of isolated prompt photons produced in association with a b -jet or a c -jet. These final states provide sensitivity to the heavy-flavour content of the proton and aspects related to the modelling of heavy-flavour quarks in perturbative QCD. The measurement uses proton–proton collision data at a centre-of-mass energy of 8 TeV recorded by the ATLAS detector at the LHC in 2012 corresponding to an integrated luminosity of up to 20.2 fb −1 . The differential cross sections are measured for each jet flavour with respect to the transverse energy of the leading photon in two photon pseudorapidity regions: |ηγ|<1.37 and 1.56<|ηγ|<2.37 . The measurement covers photon transverse energies 25<ETγ<400 GeV and 25<ETγ<350 GeV respectively for the two |ηγ| regions. For each jet flavour, the ratio of the cross sections in the two |ηγ| regions is also measured.n
