Differential cross section measurements of ${W}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\gamma}$ production in proton-proton collisions at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$ are presented. The data set used in this study was collected with the CMS detector at the CERN LHC in 2016--2018 with an integrated luminosity of $138\text{ }\text{ …
