use_mixing_alpha_onshell_scheme_rcl(s)

Sets the renormalization scheme for the mixing angle $$\alpha$$ to an on-shell or BFM scheme.

Detailed informations on the schemes are given in Table 2 in [DDL18].

Parameters: s (str) – renormalization scheme identifier s = 'OS': On-shell scheme via decays (Only HS): $$H_i \to \overline{\psi}\psi$$ s = 'OS1': On-shell scheme for decays (Only THDM): $$H_i \to \overline{\nu}_\mathrm{R}\nu$$ in Type I s = 'OS2': On-shell scheme for decays (Only THDM): $$H_i \to \overline{\nu}_\mathrm{R}\nu$$ in Type II s = 'BFM': BFM symmetry relation.
