|V_ub| for the P⁺ analyses

The same input parameters m_b(SF) and mu_pi used for the fit to all the independent analyses are used. In this case we just look at Pplus analyses.

The full breakdown of the uncertainties on the average |Vub| above is (all errors quoted in percent):

+-3.5_stat +-2.9_exp +-1.7_{b2c model} +-2.3_{b2u model} +-8.9_{HQE param} +-1.2_{SF fund} +-1.4_{sub SF} +-3.1_matching +-1.5_WA = +-11.1_tot

where the errors correspond to the statistics, the experimental systematics, the modeling of b -> c l nu and b -> u l nu decays, the HQE parameters m_b and mu_pi², the functional form of the SF, the subleading shape functions, the variation of the matching scales, and Wthe eak Annihilation. No uncertainty is assigned for possible duality violations.
