- W3711243 abstract "We compute the $widehat B_K$ parameter and the mass difference $Delta M_{LS}$ of the $K^0-bar K^0$ system by means of the chiral quark model. The chiral coefficients of the relevant $Delta S=2$ and $Delta S=1$ chiral lagrangians are computed via quark-loop integration. We include the relevant effects of one-loop corrections in chiral perturbation theory. The final result is very sensitive to non-factorizable corrections of $O(alpha_S N)$ coming from gluon condensation. The size of the gluon condensate is determined by fitting the experimental value of the amplitude $K^+ to pi^+pi^0$. By varying all the relevant parameters we obtain $widehat{B}_K= 0.87 pm 0.33 .$ We evaluate within the model the long-distance contributions to $Delta M_{LS}$ induced by the double insertion of the $Delta S = 1$ chiral lagrangian and study the interplay between short- and long-distance amplitudes. By varying all parameters we obtain $Delta M_{LS}^{th}/Delta M_{LS}^{exp} = 0.76 ^{+0.64}_{-0.34} .$ Finally, we investigate the phenomenological constraints on the Kobayashi-Maskawa parameter Im $lambda _t$ entering the determination of $epsilon'/epsilon$." @default.
