Abstract
Abstract We report the results of the calculations of the weak decays D+ → K(π)lνl, D0 → K(π)lνl and D+, D0 → two pseudoscalars, where use is made of the transition vector form factors D → K, D → π, obtained without free parameters in anisotropic chromodynamics (ACD). Good agreement with experiments is obtained for D+ decays, while for D0 → two pseudoscalars the W-exchange diagram, which is outside the present framework, plays an important role. We show that a simple parametrisation of these contributions works out very well, and leads to the correct determination of Γ( D 0 → K 0 K 0 ) .
