Query: First interpretation of the 750 GeV di-photon resonance at the LHC   We scrutinise the evidences recently reported by the ATLAS and CMS
collaborations for compatible 750 GeV resonances which appear in the di-photon
channels of the two experiments in both the 8 TeV and 13 TeV datasets. Similar
resonances in di-boson, di-lepton, di-jet and $t\bar t$ final states are
instead not detected. After discussing the properties and the compatibility of
the reported signals, we study the implications on the physics beyond the
Standard Model with particular emphasis on possible scalar extensions of the
theory such as singlet extensions and the two Higgs doublet models. We also
analyse the significance of the new experimental indications within the
frameworks of the minimal supersymmetric standard model and of technicolour
models. Our results show that a simple effective singlet extension of the SM
achieves phenomenological viability with a minimal number of free parameters.
The minimal supersymmetric model and the two Higgs doublet model, on the other
hand, cannot explain the 750 GeV di-photon excess. Compatibility with the
observed signal requires the extension of the particle content of these models,
for instance by heavy vector quarks in the case of the two Higgs doublet model.
