DESCRIPTION:Speakers: Piotr Janus ()\nMeasurement of electroweak boson pro
 duction in different collision systems are of great interest to understand
 ing the partonic structure of heavy nuclei\, and serve as a constraint on 
 the initial state in larger collision systems. Their production yields in 
 Pb+Pb with respect to pp collisions provide direct tests of both binary co
 llision scaling and possible modification of parton distribution functions
  (nPDF) due to nuclear effects. Further\, the p+Pb collisions provide a re
 latively clean environment to study nPDFs in detail. The ATLAS detector ha
 s a broad acceptance  with excellent performance even in the high occupanc
 y environment of central heavy-ion collisions. In this talk the latest ATL
 AS results on W and Z boson production at the center-of-mass energy of 5.0
 2 TeV are presented\, including updated precise result production in pp co
 llisions. Also photon yields are reported in 8.16 TeV p+Pb collision data\
 , and the production rates are compared to an extrapolated pp reference ba
 sed on existing 8 TeV collision data.\n\nhttps://indico.particle.mephi.ru/
