B decays into two charmed mesons in the isgur and wise theory

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

From the experimental branching ratios for the decay\(\overline B \)→D(*)\(\bar D\) s(*), evaluated within the Isgur and Wise theory, one gets\(f_{D_s^* } \)=(246±47) MeV and\(f_{D_s^* } \)=(241±36) MeV in good agreement with the value\(f_{D_s^* } \)=(232±45±20±48) MeV obtained from the measured Br(D +s →μ+ νμ).
