A method for measuring all Michel parameters describing the daughter muon polarization in the decay, i.e., , , , , and , is discussed. The application of the method to the future Super Charm-Tau Factory experiment is considered. The statistical uncertainties expected by the full data statistics (10 ab –1 ) are estimated as , , , , and . On their basis, upper limits on the coupling constants of interactions beyond the Standard Model are estimated. The New Physics scenario is considered, which can be reliably detected if the estimated accuracy of the parameter measurement is achieved.
