Abstract:
'We show how the LHAASO experiment, located in the province of Sichuan (China), can provide a unique opportunity to test new heavy candidates of Particle Dark Matter (DM) beyond the currently explored regimes, namely ~1 PeV and higher. Such scenarios are motivated by several DM models featuring different mechanisms for DM production in the early Universe. In particular, PeV mass DM can decay into Standard Model particles producing Very High Energy (VHE) diffuse gamma rays in the LHAASO sensitivity window. In a multi-messenger approach, LHAASO DM phenomenology can therefore be combined with high-energy neutrinos’ signals in order to test the Heavy DM hypothesis.'
