Is the ee gamma gamma+ Missing E(T) Event an Evidence of the Light   Axino?
  We point out that if the Peccei-Quinn symmetry breaking scale $F_a$ is in a range of the hadronic axion window ($F_a\sim 10^6$GeV), the ee$\gamma\gamma+/\!\!\!\! E_T$ event in the CDF experiment can be naturally explained by a no-scale supergravity model with a light axino. We also stress that the hadronic axion window still survives the intergalactic photon search, since a large entropy production due to the decay of Polonyi field yields a substantial dilution of the cosmic axion density.
