Radiative decays in the light-cone sum rules
The weak form factor for where is the state is
calculated in the light-cone sum rules (LCSR). Combining the quark model result
for the form factor of with being the state, we
have larger values for form factors than the previous LCSR results.
The increased form factors reduce the discrepancy between theory and the
experimental data for . Some phenomenological meanings are
also discussed.Comment: 15 pages, 4 figure
