Description
A new constraint on light bSM particle is proposed from the observed supernova explosion energy. This constraint is stronger than the established cooling bound for particles that can transfer energy to progenitor stellar envelop, such as dark photon which kinetically mixes with SM photon. This result also rules out the possibility of aiding successful supernova explosions by transferring energy from the supernova core to the shock with exotic particles.
