Abstract

Strong PCAC and a generalization of Dashen's relation for the K +−K 0 mass difference as well as non-relativistic considerations are used in order to obtain insight into the mechanism which causes the mass splitting among the charmed pseudoscalar mesons D + and D 0. We find a value of 7–8 MeV for M D +− M D 0.
