use_mixing_beta_onshell_scheme_rcl(s)

Sets the renormalization scheme for the mixing angle $$\beta$$ 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 = 'OS1': On-shell scheme for decays: $$H_a \to \overline{\nu}_\mathrm{R}\nu$$, $$H_i \to \overline{\nu}_\mathrm{R}\nu$$ in Type I s = 'OS2': On-shell scheme for decays: $$H_a \to \overline{\nu}_\mathrm{R}\nu$$, $$H_i \to \overline{\nu}_\mathrm{R}\nu$$ in Type II s = 'OS12': On-shell scheme for decays: $$H_a \to \overline{\nu}_\mathrm{R}\nu$$, $$H_i \to \overline{\nu}_\mathrm{R}\nu$$ in Type I/II s = 'BFM': BFM symmetry relation.
