Subleading contributions to the width of the D*(s0)(2317)
We construct the effective chiral Lagrangian involving the D-mesons and Goldstone bosons at next-to-leading order taking into account strong as well as electromagnetic interactions. This allows us to disentangle-to leading order in isospin violation-the electromagnetic and the strong contribution to...

We construct the effective chiral Lagrangian involving the D-mesons and Goldstone bosons at next-to-leading order taking into account strong as well as electromagnetic interactions. This allows us to disentangle-to leading order in isospin violation-the electromagnetic and the strong contribution to the D-meson mass differences. In addition, we also apply the interaction to the decay D-s0*(2317) -> D-s pi(0) under the assumption that the D-s0* (2317) is a hadronic molecule. We find (180 +/- 110) keV for the decay width Gamma(D-s0*(2317) -> D-s pi(0))-consistent with currently existing experimental constraints as well as previous theoretical investigations. The result provides further evidence that this decay width can serve as a criterion for testing the nature of the D-s0*(2317). (C) 2008 Elsevier B.V. All rights reserved. |
