The 'a -maximization" was introduced by K. Inrtiligator and B. Wecht for finding anomalous dimensions of chiral superfields at the IR fixed points of the RG flow. Using known explicit calculations of anomalous dimensions in the perturbation theory of SQCD (with one or two additional adjoint fields), it is checked here at the three-loop level.The NSVZ β -function in SUSY theory has the form [1] :

Using the expansions of the heavy meson decay widths in the heavy quark mass and QCD sum rules for estimates of corresponding matrix elements, we calculate the

Estimates are presented for the branching ratios of several two-particle B-meson decays into flavoured scalar mesons.It seems that there are no estimates of B-meson decays into scalar mesons. The purpose of this short note is to present such estimates. As will be shown, some two-particle decays of B-mesons into scalar mesons have sufficiently large branchings to be of current interest.
