Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will
be the world's brightest neutron source. As such, it has the potential for a particle physics …

A simple way to accommodate dark matter is to postulate the existence of a hidden sector.
That is, a set of new particles and forces interacting with the known particles predominantly …

The observation of neutrons turning into antineutrons would constitute a discovery of
fundamental importance for particle physics and cosmology. Observing the n–n ̄ transition …

The violation of baryon number, $\mathcal {B} $, is an essential ingredient for the
preferential creation of matter over antimatter needed to account for the observed baryon …

Standard Model, with its present precision, predicts the neutron β β-decay time τ _ SM=
878.7 ± 0.6 τ SM= 878.7±0.6 s which is perfectly compatible with the neutron lifetime …

We enumerate the simplest models that have baryon number violation at the classical level
but do not give rise to proton decay. These models have scalar fields in two representations …

An unexplained> 4 σ discrepancy persists between “beam” and “bottle” measurements of
the neutron lifetime. A new model proposed that conversions of neutrons n into mirror …

It has been proposed that there could be a mirror copy of the standard model particles,
restoring the parity symmetry in the weak interaction on the global level. Oscillations …

The oscillation of neutron n into mirror neutron\(n'\), its mass degenerate partner from dark
mirror sector, can gradually transform the neutron stars into the mixed stars consisting in part …
