Laboratory constraints on peV-scale mass splitting between ordinary and sterile neutron states
N. J. Ayres, Z. Berezhiani, G. Bison +19
Sterile states of matter, represented by a parallel ``mirror'' sector, may contribute to the observed dark matter in the Universe. We investigated the parameter space of neutron $(…

New high-sensitivity search for neutron to mirror-neutron oscillations at the PSI UCN source
N. J. Ayres, Z. Berezhiani, G. Bison +19
In a search for potential signals of neutron (n) to mirror-neutron (n') oscillations, a collaboration centered at the Paul Scherrer Institute (PSI) investigated the remaining param…

Baryon Number Violation: From Nuclear Matrix Elements to BSM Physics
Leah J. Broussard, Andreas Crivellin, Martin Hoferichter +19
Processes that violate baryon number, most notably proton decay and transitions, are promising probes of physics beyond the Standard Model (BSM) needed to understand the…
