First Measurement of Z+$\gamma$ Production in 13-TeV Proton-Proton Collisions

This initial study of $Z(\mu^{+}\mu^{-} )\gamma$ events from proton-proton collisions at 13 TeV compares this new data to Standard-Model (SM) predictions, as well as searches for evidence of beyond-the-Standard-Model (BSM) processes. It was found that the data generally agree with SM predictions, with no evidence for BSM physics.
