Calculation of the D+→ anti ksup(0)esup(+)ωsub(e) transition formfactor and the Usub(cs) element of the Kobajashi-Maskawa matrix
Description
QCD sum rules for a three-point vertex function are used to determine the formfactor of vector current induced D+ → anti K0 transition. The following value is obtained fsub(+)sup(D → K) (0)=0.6+-0.1, as well as the constraint on the Usub(cs) element of the Kobayashimaskawa matrix, 0.9 < or approximately Usub(cs) < 0.97
