Título : K anti-K mixing in the standard model

Resumen: We present a new calculation of the B parameter which governs the short distance contribution to the K anti-K off-diagonal mass matrix. The calculation combines the information provided by the effective chiral lagrangian realization of QCD at long distances with the perturbative behaviour of QCD at short distances via the local duality approach. The result exhibits an explicit renormalization scale dependence which exactly cancels with the corresponding dependence in the Wilson coefficient.
