An intriguing paper by ATLAS collaboration on unknown resonance of approximately 2 TeV mass. The results were obtained during the first LHC run. It seems that we have to wait till the second run is finished in order to get more accurate results.
2.5σ events are, of course, to be expected and nothing to be excited about. They're, essentially, useful for calibration purposes. A nice analysis is here; http://resonaances.blogspot.fr/2015/06/on-lhc-diboson-excess.htmlJun 18, 2015
