Polarized observables in $\tau \to VV{\nu }_{\tau }$ decays

Vindhyawasini Prasad, Hiroyuki Umeeda

We study polarization observables in ${\tau }^{-}\to V_1^{-}{V}_2^0{\nu }_{\tau }$ decays for $(V_1^{-},V_2^0)=({\rho }^{-},{\rho }^0),({\rho }^{-},\omega ),(K^{\ast -},{\rho }^0),(K^{\ast -},\omega ),({\rho }^{-},{\bar{K}}^{\ast 0})$ using the helicity…
