Description
Early results from the Run-II of the Large Hadron Collider as recently presented by the ATLAS and CMS experiments show hints of an excess in the di-photon mass spectrum near 750 GeV. While these hints might well turn out to be statistical fluctuations in the long run, they could also be first indications of a new physics phenomenon pointing beyond the Standard Model. Since the presentation of these measurements, a large number of theoretical studies have proposed possible explanations of such a signal if it should prevail. This forum reviews the experimental findings of both experiments, and presents possible interpretations for a di-photon resonance in this mass range.
