In this work, we have studied hadronic charmless two-body B decays involving p-wave mesons in the final state. We have calculated branching ratios of B - > AT decays (where A and T denote a 3P1 axial-vector and a tensor meson, respectively), using B - > T form factors obtained in the covariant light-front (CLF) approach and the full effective Hamiltonian. We have obtained that,, (with f1 = f1(1285), f1(1420)) for, with, for where K1 = K1(1270), K1(1400). It seems that these decays can be measured in experiments at B factories. Additionally, we have found that and ratios could be useful to determine numerical values of mixing angles and, respectively.
