Abstract
In this paper the dominant decay of top quark i.e. t bW → (BR=95.7%) and in particular, decay of the top quark into a bottom- quark plus a pseudoscalar or vector meson (t bm → ) are studied. we want to study this channel with the QCD factorization method. The corresponding partial widths and branching ratios are computed in LO in the non-relativistic QCD Factorization approach. Also, we have used the results of our calculations for the form factor of weak transition of a top quark into a bottom quark with the BSW method on our present work.
