Recent Paper: Narrow or Wide? The Phenomenology of 750 GeV Diphotons

Pretty much everything I know now about the anomaly at 750 GeV.  Read this, and you'll know it too. It’s nothing too certain, but I expected that going in. 3.6σand 2.6σ is just not that much significance to start with, so any question I ask would have conflicting and uncertain results, with at best only minor preferences for any particular result. But I internalized a lot about the experimental results by forcing myself to grind through the data, and once you’ve done that much work it seemed silly not to write a paper about it.

Diphotons at 750 GeV

Yesterday was the first data release of the LHC Run-II, and there has been a lot of interest in the first hints of something new. I’m skeptical, and wishing for more data. There are some suspicious tensions with previous results, but it’s certainly not clearly wrong, and its definitely the most intriguing sign of something new since the Higgs discovery. Unfortunately, we’ll have to wait at least a year to get more data to directly speak to this anomaly. It will be a difficult wait. But while we wait, read this to find out more of what we're looking at.
