We discuss the angular distribution of dilepton pairs in p+A collisions at LHC at low momentum transfer and transverse momentum. This includes helicity amplitudes and angular coefficients as well as a look at the Lam-Tung sum rule. We use leading twist NLO calculations and higher twist corrections by double scattering in large nuclei.
