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…

RV-exoplanet eccentricities: Good, Beta, and Best
A. T. Stevenson, C. A. Haswell, J. P. Faria +4
We examine the eccentricity distribution(s) of radial velocity detected exoplanets. Previously, the eccentricity distribution was found to be described well by a Beta distribution…
