Photon production, also in association with jets, is an important probe of the quark gluon plasma. For many decades, theoretical predictions of prompt photon production have been based on next-to-leading order (NLO) calculations. We present a recalculation of this process at NLO and combine it with parton showers (PS) in the POWHEG framework. This allows for the first time full NLO+PS...

Hard probes are often analyzed to study the properties of the matter created in heavy-ion collisions, by comparing the measurements to those in p+p collisions. Direct photons, those produced during the collision rather than from decays of hadrons, are particularly interesting because they do not interact strongly and thus are not affected significantly by the medium. With the photon energy...

Two particle jet correlations, especially those involving prompt photons remain an important probe of jet quenching, complementary to full jet reconstruction measurements, especially at the lowest jet energies accessible in relativistic heavy ion collisions. For gamma-jet processes, this is due to the fact that the photon can escape unbiased by the geometry of the quenching fireball, and that...
