- 論文の詳細を見る
It is examined whether O^+(Q^2Q^^-^2) states in the s-channel of D-meson decays become relatively important when QQ^^- contributions are suppressed. The strength of the weak transition to intermediate O^+(Q^2Q^^-^2) states is estimated on the basis of the relativistic composite (or Bag-like) model, and a sufficiently large contribution to the decay probability of D^0-meson is obtained when the relevant O^+ states have large widths (≳200 MeV) as well as masses not far from the D-meson mass. O^+(Q^2Q^^-^2) intermediate states with strangeness -1 formed through decay of the c-quark in the D^+-meson are limited to the SU(3) flavor 27 representation. Thus, we obtain one of possible mechanisms solving the problem of D^0- and D^+-lifetimes.
