Constraints on higher-order perturbative corrections in b $\rightarrow$ u semileptonic decays from residual renormalization-scale dependence
(IOP Publishing, 2002-04-22)The constraint of a progressive decrease in residual renormalization scale dependence with increasing loop order is developed as a method for obtaining bounds on unknown higher-order perturbative corrections to ...
