"Search for spin-dependent 5 forces in neutron whispering gallery effects"

Voronin Aleksey Yuryevich (Lebedev Physical Institut, Doctor of physics and mathematics, Leading researcher at the Laboratory of Theoretical Nuclear Physics)

The dynamics of the neutron spin in whispering gallery states is considered in the case of the presence of hypothetical spin-dependent interactions between nucleons (axion-like interactions). It is shown that such an interaction generates an additional field acting on the spatial and spin variables of the neutron. The manifestations of this field in the scattering and polarization of neutrons on a cylindrical mirror in whispering gallery states, the sensitivity to 5 forces of physical observables in different types of scattering experiments are discussed.
