Cancelling Juttner Distributions for Space-like Freeze-out
  We study freeze out process of particles across a three dimensional space-time hypersurface with space-like normal. The problem of negative contribution is discussed with respect to conservation laws, and a simple and practical new one-particle distribution for the post FO side is introduced, the Cancelling Juttner distribution.
