摘要
Goldstone boson decays of P-wave D(s)** mesons are studied within the framework of heavy hadron Chiral perturbation theory. We first analyze the simplest single kaon decays of these strange charmed mesons. We derive a model-independent prediction for the width of D(s2) and use experimental information on D(s1) to constrain the S-wave contribution to D1(0) decay. Single and double pion decay modes are then discussed and shown to be signifiCantly restricted by isospin conservation. We conclude that the pion chanNels may offer the best hope for detecting one strange member of an otherwise invisible P-wave flavor multiplet.
