英文摘要	In this article, we calculate the form-factors of the transitions B -> a(1)(1260), b(1)(1235) in the leading-order approximation using the light-cone QCD sum rules. In calculations, we choose the chiral current to interpolate the B-meson, which has the outstanding advantage that the twist-3 light-cone distribution amplitudes of the axial-vector mesons make no contributions, and the resulting sum rules for the form-factors suffer from far fewer uncertainties. Then we study the semi-leptonic decays B -> a(1)(1260)vertical bar(nu) over bar (1), b(1)(1235)vertical bar(nu) over bar (1) (1=e, mu, tau), and make predictions for the differential decay widths and decay widths, which can be compared with the experimental data in the coming future.
