Theory of $B\to \tau \nu$ and $B\to D^{(*)} \tau \nu$

TL;DR

This paper reviews how physics beyond the Standard Model could influence third-generation leptonic and semileptonic B decays, focusing on $B\to \tau \nu$ and $B\to D^{(*)} \tau \nu$ processes.

Contribution

It provides a comprehensive overview of potential new physics effects in specific B decay channels involving tau leptons.

Findings

Possible deviations from Standard Model predictions in B decays involving tau leptons.

Constraints on new physics models from current B decay measurements.

Guidance for future experimental searches for beyond Standard Model effects.

Abstract

We review possible impact of beyond Standard Model physics in the third generation leptonic and semileptonic B decays.
