Dark matter implications of the neutron anomaly

Motivated by the neutron decay anomaly, we reconsider the neutron decay model $n \rightarrow χχχ$, where the new species $χ$ plays the role of dark matter. We precisely compute the $\barχ n \rightarrow χχ$ rate finding that fitting the anomaly compatibly with all bounds needs two ''generations'' of the $χ$ particle.
