Abstract
Measurements of isolated prompt photon and massive electroweak (W and Z) boson production in different collision
systems are of great interest to understand the partonic structure of heavy nuclei, and serve as a constraint on the
initial state in larger collision systems. These channels are sensitive to a variety of effects such as the modification
of the parton densities in nuclei in certain kinematic regions, and the energy loss of partons as they undergo multiple
interactions in the nucleus before the hard parton-parton scattering. High-statistics samples of lead–lead and proton–
lead collision data at
√
sNN=5.02 TeV and 8.16 TeV, respectively, taken by the ATLAS experiment at the LHC, as well
as proton–proton comparison data at analogous collision energies, allow for a detailed study of these phenomena in
data and comprehensive comparisons to the predictions of a variety of theoretical approaches. This paper presents the
latest ATLAS results in these topics, including updated results on inclusive prompt photon production in proton–lead
collisions over a broad kinematic range and high-precision W boson results in lead–lead collisions.
