Semileptonic Bs ->DsJ(2460)l nu decay in QCD
Using three point QCD sum rules method, the form factors relevant to the
semileptonic Bs ->DsJ (2460)l nu decay are calculated. The q2 dependence of
these form factors is evaluated and compared with the heavy quark effective
theory predictions. The dependence of the asymmetry parameter alpha,
characterizing the polarization of DsJ meson, on q2 is studied .The branching
ratio of this decay is also estimated and is shown that it can be easily
detected at LHC.Comment: 21 pages, 5 figures and 1 Tabl
