Rare meson decays are among the most sensitive probes of both heavy and light new
physics. Among them, new physics searches using kaons benefit from their small total decay …

The status of tests of the standard electroweak model and of searches for new physics in
allowed nuclear β decay and neutron decay is reviewed including both theoretical and …

We report an improved measurement of the free neutron lifetime τ n using the UCN τ
apparatus at the Los Alamos Neutron Science Center. We count a total of approximately 38× …

There is a long-standing discrepancy between the neutron lifetime measured in beam and
bottle experiments. We propose to explain this anomaly by a dark decay channel for the …

The effect of dark matter (DM) on f-mode oscillations in DM admixed neutron stars (NSs) is
investigated in a comprehensive analysis with particular attention to the role of the nuclear …

Dark sector particles at the GeV scale carrying baryon number provide an attractive
framework for understanding the origin of dark matter and the matter-antimatter asymmetry …

Exotic particles carrying baryon number and with a mass of the order of the nucleon mass
have been proposed for various reasons including baryogenesis, dark matter, mirror worlds …

The neutron lifetime anomaly has been used to motivate the introduction of new physics with
hidden-sector particles coupled to baryon number, and on which neutron stars provide …

A bstract We add to the Standard Model a new fermion χ with minimal baryon number 1/3.
Neutron decay n→ χχχ into non-relativistic χ can account for the neutron decay anomaly …

In this work, we perform the first systematic investigation of effects of the presence of dark
matter on r-mode oscillations in neutron stars (NSs). Using a self-interacting dark matter …
