B-S transition form-factors with the light-cone QCD sum rules
Abstract
In the article, we assume the two scalar nonet mesons below and above 1 GeV are all qq states, in case I, the scalar mesons below 1 GeV are the ground states, in case II, the scalar mesons above 1 GeV are the ground states. We calculate the B-S form-factors by taking into account the perturbative O(αs) corrections to the twist-2 terms using the light-cone QCD sum rules and fit the numerical values of the form-factors into the single-pole forms, which have many phenomenological applications.
