Rescattering effects can modify the dependence on the weak phase γ = −Arg(V ∗ ubVud/V ∗ cbVcd) of the ratio of rates for B → Kπ and B → Kπ. A test for these effects based on the processes B → KK has been suggested. It is pointed out that the rates for the processes B → KK, which are expected to be dominated by rescattering and for which considerably better experimental bounds exist, are likely ...

In the framework of semihard QCD approach, with the emphasis on the BFKL evolution of gluon distributions, we calculate the differential cross sections of inclusive D mesons electroproduction at HERA and confront our results with available ZEUS experimental data.

We construct the B.S. equation for baryons. The most general form of the B.S. wave function is given. In the heavy quark limit we show clearly that the spin symmetry exists in heavy baryon states.
