What can we learn from the radiative decays of the D s 1 ( 2460 ) meson?
Abstract
We study the radiative decays D s 1 ( 2460 ) → γ D s 0 * ( 2317 ) and D s 1 ( 2460 ) → γ D 0 K + / γ D + K 0 and argue them to constitute a paradigmatic case of reactions sensitive to the short-range component of the decaying meson wave function that can, in principle, be quantified in a model-independent way employing experimental data. We demonstrate how a simultaneous measurement of the above radiative decay widths, or at least a constraint on the ratio of the corresponding branching fractions, can allow one to probe the nature of the D s 0 * ( 2317 ) and D s 1 ( 2460 ) mesons.
