Back in December 2015, there was found a 750 GeV diphoton excess in both CMS and ATLAS at the same location with a significance well above $3\sigma$; a 0.13% chance of being false.
However, there hasn't been any recent rumours on a well known blog confirming that this diphoton excess is increasing with 2016 data, currently $13.5 fb^{-1}$ from both ATLAS and CMS. In my opinion, it's now looking likely that the 750Gev diphoton excess is disappearing in both detectors, despite both signals being seen at the same location, and having a local 0.13% chance of being false!
The Look Else Where Effect has the effect of making it likely that a statistically insignificant local event is likely to occur somewhere over a large parameter space. I would like to know: what are the chances that a false $3\sigma$ diphoton excess will be detected at the LHC?
