Discovery potential and characterisation of the parity properties of a new spin-0 boson at the LHC and HL-LHC.

Abstract: We investigated the discovery potential and possibilities of characterizing the parity of a new spin-0 boson at LHC and HL-LHC only using di-photon channel. Our results show that it is possible to have a 5σ discovery and characterize the parity at 2σ level for given combinations of couplings and masses.
