The -meson Wave Functions in QCD Sum Rules Approach with Nonlocal Condensates

We apply the nonlocal condensate formalism to construct generalized sum rules (including O(s)-radiative corrections) for- ,-and 0-meson wave functions of twist 2. Besides, we predict the lepton decay constant f 0 and estimate the mass of 0-meson. For all these mesons we obtain the rst 10 moments of longitudinal wave functions , suggest the models for them and discuss their properties. We consider the peculiarities of the QCD sum rules with nonlocal conden-sates for transverse-and b 1-meson wave functions. These results are compared with those found by Ball and Braun and by Chernyak and Zhitnitsky.
