Isgur-Wise function in the relativistic quark model
- CCAST (World Laboratory), P.O. Box 8730, Beijing 100080, Peoples Republic of (China)
The Isgur-Wise function {xi}(v{center_dot}v{sup {prime}}) is given in the Bethe-Salpeter formalism. By introducing a phenomenological interaction kernel, we calculate its numerical result. We find that the absolute slope of {xi}(v{center_dot}v{sup {prime}}) at the zero recoil point v{center_dot}v{sup {prime}}=1 is larger for the process in which the involved light degree of freedom is an s quark rather than for the case of u,d quarks. Our results agree with others. {copyright} {ital 1997} {ital The American Physical Society}
