Abstract
An improved calculation of susy-corrections to theK L →2γ process is done, including also the charged-Higgs contributions. The Higgsino-Wino mixings are carefully considered and the results are presented as a function of a susy-breaking parameter. An evaluation of the diagrams which include supersymmetric penguins is also done, finding a contribution somewhat lower than the previous one. We conclude that the Higgs and susy amplitudes are smaller than the standard amplitude.
