Constraining Dark Boson Decay Using Neutron Stars

Inspired by the well-known anomaly in the lifetime of the neutron, we investigated its consequences inside neutron stars. We first assessed the viability of the neutron decay hypothesis suggested by Fornal and Grinstein within neutron stars, in terms of the equation of state and compatibility with observed properties. This was followed by an investigation of the constraint information on neutron star cooling that can be placed on the decay rate of the dark boson into standard model particles, in the context of various BSM ideas.

Automated summary

Inspired by the anomaly in neutron lifetime, this study investigates its effects inside neutron stars. Firstly, the viability of the neutron decay hypothesis proposed by Fornal and Grinstein within neutron stars is assessed, considering the equation of state and compatibility with observed properties. Subsequently, the constraint information on neutron star cooling, in relation to the decay rate of the dark boson into standard model particles, is examined within the context of various beyond the standard model (BSM) ideas.
