### Description

We discuss the possibilities for observing the new physics effects at low energies through a detailed analysis of the angular distribution of the decay products. In particular we find new observables that are accessible experimentally and that can be very useful in searches for the effects of physics beyond the Standard Model at low energies. We show the potential of this research on a specific example of $B\to D\ell\nu$ and $B\to D^\ast \ell \nu$ decays.
