Neutron lifetime puzzle and neutron–mirror neutron oscillation [PDF]
The European Physical Journal C, 2019 The discrepancy between the neutron lifetimes measured in the beam and trap experiments can be explained via the neutron $n$ conversion into mirror neutron $n'$, its dark partner from parallel mirror sector, provided that $n$ and $n'$ have a tiny mass splitting order $10^{-7}$ eV.

Constraints on physics of neutron stars from X-ray observations [PDF]
, 2013 I summarize some constraints on the physics of neutron stars arising from X-ray observations of the surfaces of neutron stars, focusing on using models of low-magnetic-field neutron star atmospheres to interpret their X-ray spectra.
