چکیده
Using three point QCD sum rules method, the form factors relevant to the semileptonic Bs → DsJ(2460)lν decay are calculated. The q2 dependences of these form factors are evaluated and compared with the heavy quark effective theory predictions. The dependence of the asymmetry parameter α, characterizing the polarization ofDsJ 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.

With the identification of (DsJ (2317), DsJ (2460)) as the (0 , 1) doublet in the heavy quark effective field theory, we derive the light cone QCD sum rule for the coupling of eta meson with DsJ (2317)Ds and DsJ (2460)D ∗ s . Through η − π 0 mixing we calculate their pionic decay widths, which are consistent with the experimental values (or upper limits). Combining the radiative decay widths de...

We calculate D+ s → φ transition form factors V , A0, A1 and A2, and study semileptonic decay of D+ s → φl̄ν based on QCD sum rule method. We compare our results of the ratios of V (0)/A1(0), A2(0)/A1(0), ΓL/ΓT , and the total decay branching ratio of D+ s → φl̄ν with experimental data, and find that they are consistent.
