Generalized heavy-to-light form factors in light-cone sum rules
Generalized heavy-to-light form factors in light-cone sum rules
We study the form factors for a heavy meson into the S-wave Kπ/ππKπ/ππ system with an invariant mass below 1 GeV. The mesonic final state interactions are described in terms of the scalar form factors, which are obtained from unitarized chiral perturbation theory. Employing generalized light-cone di...

We study the form factors for a heavy meson into the S-wave Kπ/ππKπ/ππ system with an invariant mass below 1 GeV. The mesonic final state interactions are described in terms of the scalar form factors, which are obtained from unitarized chiral perturbation theory. Employing generalized light-cone distribution amplitudes, we compute the heavy-to-light transition using light-cone sum rules. Our approach simultaneously respects constraints from analyticity and unitarity, and also takes advantage of the power expansion in the 1/mb1/mb and the strong coupling constant. |
