A Complete Framework for Tau Polarimetry in $B\to D^{(\ast )}\tau \nu$ Decays

Pouya Asadi, Anna Hallin, Jorge Martin Camalich +2

The meson decays $B\to D\tau \nu$ and $B\to D^{\ast }\tau \nu$ are sensitive probes of the $b\to c\tau \nu$ transition. In this work we present a complete framework to obtain the maximum information on t…
