Description
Current measurements of the branching fractions for b --> c tau nu processes yield results that are more than 4 standard deviations higher than the standard-model expectations. This motivates exploration of potential new physics in these decays, including searches for CP violation. A CP-violating asymmetry requires interference between amplitudes with different CP-violating and CP-conserving phases. We show that these conditions can be satisfied in B --> D** tau nu in the presence of new physics, and describe a new method for measuring the asymmetry at Belle II or LHCb.
