Frame Dependence of Parton Cascade Results
  Frame dependence of parton cascade results is studied for different schemes of doing cascade simulations. We show that different schemes do not always agree and results may have strong frame dependence. When the interaction range is on the order of mean free path and the collisions are done in the two particle center of mass frame, the results are not sensitive to the global frame that the collisions are ordered. Effects of different differential cross sections are also discussed.
