Semianalytical model of optical cavity-assisted photon–nucleon coupling

Abstract

We propose a semianalytical method to evaluate photon–nucleon interaction. Our method is based on adding an optical cavity to the neutron decay process. This model is an extension of the classical Fermi’s beta decay model, which satisfactorily considers the effects of optical cavities on nuclear decay. The numerical simulation results show that this model may explain the neutron lifetime problem in the present experiment. Finally, we discuss the discrepancy in current methods of measuring neutron lifetime, which may be caused by different experimental setups.
