Query: Gluino-squark contributions to CP violations in the kaon system   Recently it was shown, within the mass insertion approximation (MIA), that
the gluino mediated flavor changing neutral current (FCNC) interactions can
saturate both epsilon_K and Re(epsilon'/epsilon_K) even for the real
Cabibbo-Kobayashi-Maskawa (CKM) matrix through a single CP violating parameter
(delta^d_12)_LL. In this work, we extend our previous analysis to the
nonvanishing KM phase, and to the effective SUSY model where the MIA is no
longer a good approximation. In our model, epsilon_K and B0 - B0 bar mixing can
receive significant SUSY contributions. Therefore the usual constraints on rho
and eta in the Wolfenstein parametrization of the CKM matrix can be relaxed
except for the |V_ub/V_cb| from the semileptonic b -> u transition. This
affects K -> pi nu nu bar and K_L -> mu+ mu- indirectly, even if they are not
directly induced by gluino-mediated FCNC, while K_L -> pi0 e+ e- is influenced
both directly and indirectly. Differences between our model and other SUSY
models enhancing Re(epsilon'/epsilon_K) are discussed in detail.
