Photon-jet production and angular correlations in proton-nucleus collisions: from low to high $p_t$

We calculate the photon-jet production cross section in proton-nucleus collisions extending the previous calculations, done in the small $x$ (low $p_t$) limit, to high $x$. This allows one to investigate the disappearance and re-appearance of the away side peak in azimuthal angular correlations from low to high $p_t$ as well as the forward-backward rapidity correlations.
