Abstract
The existence of a 750 GeV di-photon spin-0 resonance would imply the additional presence of new particles beyond the Standard Model, coupling directly to and electromagnetically charged. For an singlet , we explore the possibility of probing the and quantum numbers of the new states at the LHC by measuring and constraining the , , and decays of . We obtain robust prospects on the required LHC integrated luminosity to discover the new decay modes of and discuss the implications of these measurements for probing the electroweak nature of the new states. We also discuss the impact of mixing with the SM Higgs in such probes.
