Novel neutron decay mode inside neutron stars

We explore the suggestion that neutron lifetime puzzle might be resolved by neutrons decaying into dark matter through process, n \rightarrow \chi\chi\chi, with \chi having a mass one third of neutron. In particular, we examine consequences such decay mode for properties stars. Unlike an earlier suggested mode, in order to satisfy constraints on star and tidal deformability, there is no need strong repulsive force between particles. This study suggests possibility hot at core presents possible mechanism cooling, examines signal this way inside right after its birth.
