K$^{0}$-$\overline{K}^{0}$ mixing and the CKM parameters ($\varrho$,$\eta$) from the Laplace sum rules
Using the Laplace sum rule (LSR) approach, which is less affected by the contribution of the higher mass hadronic states than the Finite Energy Sum Rule (FESR), we test the reliability of the existing estimate of the K^0-\overline {K}^0 mixing parameter from the four-quark two-point correlator. We o...
