  We investigate the experimentally-accessible kinematic distributions of the
$\bar B\to D^{(*)}\tau^-(\to\ell^-\bar\nu_\ell\nu_\tau)\bar\nu_\tau$ decays.
Specifically, we study the decay rates as functions of the $B\to D^{(*)}$
transferred squared momentum, the energy of the final charged lepton and the
angle of its 3-momentum relative to the 3-momentum of the recoiling $D^{(*)}$.
The angular distribution allows to introduce new observables, like a
forward-backward asymmetry, which are complementary to the total rates. We
present analytic formulas for the observable 3-fold 5-body differential decay
rates, study the predictions in the Standard Model and investigate the effects
in different new-physics scenarios that we characterize using an effective
field theory framework.
