A study of time reversal violation in two mechanisms through spin dependent total cross section measurements

Abstract

In the minimal standard model, MSM, if CP violation is included via the CKM matrix, spin dependent cross sections odd under time-reversal vanish. However these cross sections are not necessarily zero if the MSM is extended to include new CP violating mechanisms, e.g., through the exchange of neutral or charged Higgs bosons. Thus a precision measurement of T-odd total cross sections using polarized beams and targets could be a valuable test of time-reversal asymmetries and their mechanisms.
