CALCULATION OF THE K-MESON FORM-FACTOR BY MEANS OF THE PRINCIPAL VALUE METHOD

The K-meson electromagnetic form factor F-K(Q(2)) is calculated by using the principal value method, which allows one to regulate endpoint ir singularities of QCD running coupling constant alpha(S)(Q(2)xy) (alpha(S)(Q(2)(1 - x)(1 - y))) in the soft x --> 0, y --> 0 (x --> 1, y --> 1) region by expressing it in terms of the alpha(S)(Q(2)). In calculations the K-meson sum rules wave function is used.
