Effects of The Initial Hadron in $B o J/psi+X$ | | J.P. Ma

7 Jun 2000 | | Journal: | Phys.Lett. B488 (2000) 55-62 | | Subject: | hep-ph | | Abstract: | In the framework of HQET inclusive decays of b-flavored hadrons can be handled as decays of the free b-quark approximately. We analyse the correction to this approximation for the inclusive decays into a polarized $J/psi$,the correction is characterized by two matrix elements defined in HQET. For the $J/psi$ we use NRQCD to parameterize the formation of the $car c$ pair into $J/psi$. Numerically the correction is remarkably large, it can be at the level of 30% and it is mainly due to the Fermi-motion of the $b$-quark. With this correction we give a new determination for combinations of two NRQCD matrix elements. | | Source: | arXiv, hep-ph/0006060 | | Services: | Forum | Review | PDF | Favorites | |
