Complete framework for tau polarimetry in B →D<SUP>(*)</SUP>τ ν decays
The meson decays B →D τ ν and B →D *τ ν are sensitive probes of the b →c τ ν transition. In this work, we present a complete framework to obtain the maximum information on the physics of B →D (*)τ ν with polarized τ leptons and unpolarized D (*) mesons. Focusing on the hadronic decays τ →π ν and τ →ρ ν , we show how to extract seven τ asymmetries
