Abstract
We discuss a possible interpretation of the Ds1(2460) meson as a hadronic molecule - a bound state of D* and K mesons. Using a phenomenological Lagrangian approach we determine the strong Ds1 to Ds* pi0 and radiative Ds1 to Ds gamma decays. In order of magnitude our results for the partial strong and radiative decay widths are consistent with previous calculations.
