New Physics in B —→ D^(*) ℓ ν_ℓ — •Kilian Lieret and Thomas Kuhr — LMU, Munich, Germany

Measurements of B —→ D^(*) ℓ ν_ℓ branching fraction ratios currently challenge lepton universality and thus the Standard Model at a four sigma level. This talk focuses on how to discriminate between different kinds of possible new physics contributions. Based on the full angular distribution of the decay, several observables for different new physics scenarios are considered. Furthermore, we will reanalyze Belle I data in order to provide more specific distributions for phenomenological studies.
