In December, the ATLAS and CMS experiments reported what could be the first hint of a new massive particle that spits out two photons as it decays. Now, physicists are presenting their latest analyses, including a full investigation of this mysterious bump. Both experiments have come to the same conclusion -- the bump is still there.
Physicists working at the Large Hadron Collider reported an unusual bump in their signal. But this time, they have no idea where the bump came from.
