Interpretation of D(2637) from heavy quark symmetry

Abstract

We demonstate from heavy quark symmetry that the width of D(2637) claimed by the DELPHI Collaboration is inconsistent with any bound state with one charm quark predicted in the D(2637) mass region, except possibly D*_3, D_2 or D'. The former two possibilities are favoured by heavy quark mass relations.
