A search for neutron-to-hidden-neutron oscillations in a ultra-cold neutron beam
G. Ban, J. Chen, P. -J. Chiu +11
Models that postulate the existence of hidden sectors address contemporary questions, such as the source of baryogenesis and the nature of dark matter. Among the possible mixing pr…
A search for neutron to mirror-neutron oscillations
C. Abel, N. J. Ayres, G. Ban +40
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 betw…
A global perspective on searches for Electric Dipole Moments
Guillaume Pignol
Many experiments are underway in the world to search for a non-zero electric dipole moment (EDM) of a particle with spin 1/2 such as the neutron or the electron. Finding an EDM wou…
Acoustic Rabi oscillations between gravitational quantum states and impact on symmetron dark energy
Gunther Cronenberg, Philippe Brax, Hanno Filter +6
The standard model of cosmology provides a robust description of the evolution of the universe. Nevertheless, the small magnitude of the vacuum energy is troubling from a theoretic…
Bounding Quantum Dark Forces
Philippe Brax, Sylvain Fichet, Guillaume Pignol
Dark sectors lying beyond the Standard Model and containing sub-GeV particles which are bilinearly coupled to nucleons would induce quantum forces of the Casimir-Polder type in ord…
Search for axion-like dark matter through nuclear spin precession in electric and magnetic fields
C. Abel, N. J. Ayres, G. Ban +45
We report on a search for ultra-low-mass axion-like dark matter by analysing the ratio of the spin-precession frequencies of stored ultracold neutrons and Hg atoms for an a…
