Abstract

We discuss a possible interpretation of the

D_{s 1} (2460)

meson as a hadronic molecule—a bound state of

D^{*}

and

K

mesons. Using a phenomenological Lagrangian approach we determine the strong

D_{s 1} \to D_{s}^{*} π^{0}

and radiative

D_{s 1} \to D_{s} γ

decays. In order of magnitude, our results for the partial strong and radiative decay widths are consistent with previous calculations.
