We calculate the vector and axial-vector form factors of \$B\_u,d,s\$ decays
into P-wave axial-vector mesons in the light-cone sum rule approach. For the
sum rule results, we have included corrections of order \$m\_A/m\_b\$, where \$m\_A\$
is the mass of the axial-vector meson \$A\$. The results are relevant to the
light-cone distribution amplitudes of the axial-vector mesons. It is important
to note that, owing to the \$G\$-parity, the chiral-even two-parton light-cone
distribution amplitudes of the \$^3P\_1\$ (\$^1P\_1\$) mesons are symmetric
(antisymmetric) under the exchange of quark and anti-quark momentum fractions
in the SU(3) limit. For chiral-odd light-cone distribution amplitudes, it is
the other way around. The predictions for decay rates of \$B\_u,d,s A e
\nu\_e\$ are also presented.
