On the Neutron Transition Magnetic Moment

Understand

We discuss the possibility of the transition magnetic moments (TMM) between the neutron n and mirror neutron n', its hypothetical sterile twin from parallel particle "mirror" sector.

• The neutron can be spontaneously converted into mirror neutron via these TMM's (in addition to the more conventional transition channel due to n-n' mass mixing) interacting with the magnetic field B as well as with mirror magnetic field B'.
• We derive analytic formula for the average probability of n-n' oscillation and consider possible manifestations of the neutron TMM effects.
• In particular, we discuss potential role of these effects in the neutron lifetime measurement experiments leading us to new, testable predictions.
