Study On The Decay Of B Meson To Axis Vector Meson

Study on B meson decays into an axial vector meson is very important in B physicstheory.In this paper a new version of LCSR (we call it B-meson LCSR) is developedfurther.we calculate the B b11235form factors with the B-meson light-cone QCD sum rules. Those form factors are basic parametersin studying the exclusive non-leptonic two-body decays.Ournumerical results are consistent with the values from the (light-cone) QCD sumrules.The main uncertainty comes from the parameter0(or B), which determinesthe shapes of the two-particle and three-particle light-cone distribution amplitudesof the B-meson, it is of great importance to refine this parameter.
