Time reversal invariance violating interactions of high energy short-lived particles in bent and straight crystals

Abstract

The spin rotation phenomenon of channelled particles, moving in a bent crystal, which was theoretically predicted in [1] and observed in [2], gives us the opportunity to measure anomalous magnetic moment of high energy short-lived particles. The appearance of beams with energies up to 7 Tev on LHC and further growth of particles' energy and beams' luminosity on FCC do essentially improve the possibility of using the phenomenon of spin rotation of the high energy particles in bent crystals and spin depolarization of such particles for measuring anomalous magnetic moments of positively charged, as well as neutral and negatively charged short-lived baryons, and τ-lepton [3,4].
