Sažetak
We report on the calculation of the two-loop electroweak, two-photon mediated short-distance
dispersive K_L o mu^+mu^- decay amplitude. QCD corrections change the sign of this contribution
and reduce it by an order of magnitude. The resulting amplitude enables us to provide a constraint on
the otherwise uncertain long-distance dispersive amplitude.
