I was told that it has recently been confirmed to be spin-2 particle, and potentially to be graviton. I'm pretty interested in how this has been examined.
Edit: During the Moriond 2016 conference, CMS clearly stated it is a spin-2 rather than spin-0 particle (spin-1 has already been ruled out by Landau-Yang theorem [1-2]). For a review, see .
The yesterday report on ATLAS claims new analysis and new methods gave promising result, which is what I'm looking forward to know. Also I would like some experts to give an introduction to the physics picture how to examine the spin, and what's the theoretical model  means.
Edit2: on Aug 5th, ICHEP conference, the new result is gonna to be published.
Edit3: ICHEP conference released ATLAS & CMS results [5-6]. ATLAS doesn't contain newest spin-2 selection results (which could be something), while CMS gives disappointing results.
