A new method for measurement of the Michel parameters that describe the daughter muon polarization in the ${\tau }^{-}\to {\mu }^{-}{\bar{\nu }}_{\mu }{\nu }_{\tau }$ decay

D. Bodrov, P. Pakhlov

This paper provides a detailed description of the method for the first direct measurement of all Michel parameters in the ${\tau }^{-}\to {\mu }^{-}{\bar{\nu }}_{\mu }{\nu }_{\tau }$ decay related to the polarization…
