Abstract: (arXiv)

We present a brief discussion about expressions of decay widths of exclusive nonleptonic and semileptonic B decays at tree level including

l=0

and

l=1

mesons in final state. Our analysis is carried out assuming factorization hypothesis and using parametrizations of hadronic matrix elements given in WSB and ISGW quark models. Special interest is focused on dynamics of these processes and several important ratios between decay widths to determine form factors and decay constants are given.

13.20.-v
12.39.-x
13.25.-k
B: hadronic decay
B: semileptonic decay
decay: exclusive reaction
B: decay modes
B: width
differential cross section
tree approximation
