  The CP-violating charge asymmetry in decays K+- --> \pi+- \gamma\gamma, which
is induced by the electromagnetic penguin operators, has been studied both in
thestandard model and in its extensions. Because of a large enhancement of the
Wilson coefficients of the electromagnetic penguin operators in the
supersymmetric extensions of the standard model, a significant upper bound on
this charge asymmetry could be expected, and thus high precision measurements
of this interesting CP-violating quantity might explore new physics effects
beyond the standard model.
