Limits on a nucleon-nucleon monopole-dipole (axionlike) P-,T-noninvariant interaction from spin relaxation of polarized ultracold neutrons

TL;DR

This paper establishes new constraints on axionlike particles by analyzing how ultracold neutrons lose polarization in traps, providing insights into P-,T-noninvariant interactions.

Contribution

It introduces a novel limit on axionlike couplings based on ultracold neutron depolarization data, advancing understanding of fundamental particle interactions.

Findings

New upper limit on axionlike coupling strength

Depolarization data constrains P-,T-noninvariant interactions

Enhanced sensitivity in neutron experiments

Abstract

A new limit is presented on the axionlike coupling from the data on the ultracold neutrons depolarization in traps.
