Heavy-to-light form factors on the light cone

High Energy Physics - Phenomenology 2008-11-26 v4

Abstract

The light cone method provides a convenient non-perturbative tool to study the heavy-to-light form factors. We construct a light cone quark model utilizing the soft collinear effective theory. In the leading order of effective theory, the ten BB to light physical form factors are reduced to three universal form factors which can be calculated as overlaps of hadron light front wave functions in the light cone quark model. The numerical results show that the leading contribution is close to the results from other approaches. The q2q^2 dependence of the heavy-to-light form factors are also presented.
