Sommaire:

Left-right symmetric model (LRSM) is a well-motivated beyond Standard Model theory, which connects the origin of parity violation to the neutrino mass. We study the viability of having dark matter candidate in the minimal such theory. We find the lightest right-handed (RH) neutrino as keV warm dark matter could be consistent with a TeV-scale window of LR symmetry. In this scenario, the early universe has to experience thermal (over) production of DM and late entropy production/dilution. We discuss the cosmological and low energy experiment constraints, as well as the discovery prospect for the theory at LHC.
