Gravity Resonance Spectroscopy (GRS) investigates the energy states of Ultra-Cold Neutrons using an equivalent of Ramsey's method of separated oscillating fields. The manipulation of states is realized using mechanical oscillations instead of EM fields. This allows direct investigation of some "beyond-Riemann" gravity models as well as specific DM and DE candidates. An overview of current...
The n2EDM experiment, which is currently being commissioned by the international nEDM collaboration at the Paul Scherrer Institute, aims to search for a non-vanishing electric dipole moment of the neutron with a sensitivity of 1x10^-27 e cm in the baseline setup. An overview of the experimental setup and the current status of the experiment will be presented.
Ultracold neutrons are indispensable probes for precision experiments in fundamental physics, providing unique opportunities to search for new physics beyond the Standard Model. This presentation will cover the principles and current status of two key experiments poised to utilize high-yield UCN sources: the TUCAN EDM experiment and the PENeLOPE neutron lifetime experiment.
The TUCAN EDM...
Angular correlation measurements can provide high precision values for the axial coupling constant in neutron decay, a fundamental input in the determination of the beta decay rate predicted by the Standard Model of particle physics. Completed in 2018, the UCNA experiment was designed to utilize polarized ultracold neutrons to perform a high precision measurement of the beta asymmetry -- the...
