Abstract (data abstract)
CERN-LHC. Search for new phenomena in high-mass diphoton final states using 37 fb^−1 of proton-proton collisions collected at a centre-of-mass energy of 13 TeV with the ATLAS detector in 2015 and 2016. The final states used are 2 photons. The fiducial region for the spin-0 resonance search is defined as: - 2 photons - E_T > 0.4 m_gamgam for the photon with leading E_T, and E_T > 0.3 m_gamgam for the photon with sub-leading E_T - |eta_gam| < 2.37 - An isolation requirement using all particles with lifetime greater than 10 ps at the generator level in a cone of Delta_R = 0.4 around the photon direction: E^iso_T< 0.05 E_T+ 6 GeV. For the spin-2 resonance search, the acceptance and efficiencies are assumed to be those obtained from MC simulation of KK graviton decays.
