|Vub| for the P+ analyses

The same input parameters mb(SF) and mupi 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):

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 mb and mupi2, 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.
