  We have studied the contribution of the high-scale SUSY to the K_L to pi^0
nu{bar nu} and K^+ to pi^+ nu{bar nu} processes correlating with the CP
violating parameter epsilon_K. Taking account of the recent LHC results for the
Higgs discovery and the SUSY searches, we consider the high-scale SUSY at the
10-50 TeV scale in the framework of the non-minimal squark (slepton) flavor
mixing. The Z penguin mediated the chargino dominates the SUSY contribution for
these decays. At the 10 TeV scale of the SUSY, the chargino contribution can
enhance the branching ratio of K_L to pi^0 nu{bar nu} in eight times compared
with the SM predictions whereas the predicted branching ratio BR(K^+ to pi^+ nu
{bar nu}) increases up to three times of the SM one. The gluino box diagram
dominates the SUSY contribution of epsilon_K up to 30%. If the down-squark
mixing is neglected compared with the up-squark mixing, the Z penguin mediated
the chargino dominates both SUSY contributions of K_L to pi^0 nu {bar nu} and
epsilon_K. Then, it is found a correlation between them, but the chargino
contribution to epsilon_K is at most 3%. Even if the SUSY scale is 50TeV, the
chargino process still enhances the branching ratio of K_L to pi^0 nu {bar nu}
from the SM prediction in the factor two, and epsilon_K is deviated from the SM
prediction in O(10%) through the gluino box diagram unless the down-squark
mixing is suppressed. We also discuss the chargino contribution to K_L to pi^0
e^+e^- process.
