BARYON POLARIZATION, PHASES OF AMPLITUDES AND TIME-REVERSAL ODD OBSERVABLES

We elaborate two different methods for extracting from data the relative phase of two amplitudes of some sequential decays of baryons. We also relate this phase to a particular physical angle. Moreover, we suggest how to infer some time-reversal (TR) odd observables — in particular, asymmetries — from data. Last, we comment on the Standard Model (SM) predictions of such asymmetries, showing that most of the decays considered are quite suitable for revealing possible new physics (NP) contributions.
