Presently work presents the branching ratios of non-leptonic two-body decays of B mesons, we have limited ourselves to the channels whose analysis and measure of their decompositions hadronicas allow us to understand the effects of the interactions electrodebiles (QED) and strong (QCD). Within the framework of naive factorization, the hadronic matrix element were calculated, that introduce the decays in two slight mesons of high energy ( ) that are expressed in terms of form factors and constant of decays. They were calculated comparing the results with the results published by good agreements with the recent experimental data CLEO, BELLE and BABAR.
