摘要：
Charmed-pseudoscalar-meson decays are discussed in a model with massive quarks. We show that the model is consistent with the known branching ratios of D→Kπ as well as a D semileptonic branching ratio of 10% provided the D-meson decay constant is significantly larger than that of the π. We predict the average D lifetime to be 5× 10-13 sec by using the experimental semileptonic branching ratio. © 1979 The American Physical Society.
