Beyond $\mathcal{R}(D^{(\ast )})$ with the general 2HDM-III for $b\to c\tau \nu$

R. Martinez, C. F. Sierra, German Valencia

We review the parameter regions allowed by measurements of $\mathcal{R}(D^{(\ast )})$ and by a theoretical limit on $\mathcal{B}(B_c\to \tau \nu )$ in terms of generic scalar and pseudoscalar n…
