Description
Isolated prompt photons provide a direct probe of short-
distance physics, complementary to that provided by measurements of
jets or vector-bosons and are sensitive to the gluon density of the
proton. The inclusive prompt photon cross sections have been measured
by the ATLAS collaboration at various centre-of-mass energies of pp
collisions over a wide range of transverse momenta. These experimental
results are reported in different fiducial regions covering a wide
acceptance and are compared to next-to-leading order QCD calculations
with different models of the parton content of the proton.
The diphoton and photon+jet system cross sections have also been
measured as a function of several kinematic variables.
