摘要：
We demonstrate 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 the D-wave orbitally excited states D-3* and D-2jq (= delta/2) or the radially excited state D'. The former two possibilities are favoured by heavy quark mass relations.
