T-violating observables in neutron decay – experimental opportunities

The neutron beta decay is a rich source of information for physics of the Standard Model and beyond. T-odd observables like D- and R-correlation coefficients are particularly interesting for searches of unknown yet sources of CP violation in the electroweak sector since in the framework that assumes validity of the CPT theorem T- and CP-violation are equivalent. In the presentation, current achievements will be reviewed and future experimental opportunities will be sketched including never before measured T-odd observables in ordinary and radiative neutron decay.
