All four ATLAS, CMS papers from 2012 and 2015 have apparently seen some excess in the Z-gamma (decaying to lepton pair and photon) at mass 350-380 GeV.

Now, it seems that 12.9/fb of the 2016 CMS data have an excess in that range, too. Is ATLAS seeing some local resonance in the Z-gamma near the mass 350-380 GeV, too?

They calculate the global significance to be 2.84 sigma or so. But it's CMS. Is there an ATLAS work on that?

It has worked great with the Z-gamma. May I ask for one more URL and scheduling of a talk if there's any? EXO-16-015 is a CMS paper seeing a 3.7-sigma (locally, ideally) excess for a 2.0 TeV excited quark in jet+photon.

Is there a similar talk or paper by ATLAS? Thanks!
