Signatures at Super-Kamiokande and neutron star for neutron dark decay models

  • PLACE Kenkyu-Honkan 1F, Meeting Room 3

We point out that two models that reconcile the neutron lifetime anomaly via dark decays of neutron, also predict dark matter-neutron annihilation, that may be observable in neutron-antineutron oscillation searches at Super-Kamiokande. We study possible signatures of photon+pion and multi-pions. Alternative, we study the interplay between neutron star and these models. Neutron star can be in hybrid state with neutron and dark matter, then the dark matter self interaction helps to capture the halo dark matter, such that heat up the old neutron star temperature, which shall be detected by near future infra-red telescopes.
