In the framework of the Weinberg-Salam model and the standard four-quark picture we have calculated the mass difference between the K/sub L/- and K/sub S/- mesons. The influence of the strong interactions at short distances has been taken into account in the framework of an asymptotically free gauge theory, and it is shown that the total effect is small. For the mass of the charmed quark we have obtained the interval 1.7< or =m/sub c/< or =2.9 GeV, owing to the indeterminacy in the contribution from large distances.
