Bounds on Heavy-to-Heavy Weak Decay Form Factors
Abstract
We provide upper and lower bounds on the semileptonic weak decay form factors for B --> D(*) and Λb --> Λc decays by utilizing inclusive heavy quark effective theory sum rules. These bounds are calculated to second order in ΛQCD/mQ and first order in αs. The O(α 2sβ0) corrections to the bounds at zero recoil are also presented.
