    "abstract": "We simulate the fragmentation processes in the \\CaCa collisions at the\nbombarding energy 1.05 GeV/u using the Lorentz covariant RQMD and the\nnon-covariant QMD approaches, incorporated with the statistical decay model. By\ncomparing the results of RQMD with those of QMD, we examine the relativistic\neffects and find that the multiplicity of the $\\alpha$ particle after the\nstatistical decay process is sensitive to the relativistic effects. It is shown\nthat the Lorentz covariant approach is necessary to analyze the fragmentation\nprocess even at the energy around \\Elab = 1 GeV/u as long as we are concerned\nwith the final observables of the mass distribution, particularly, the light\nfragments around $A = 3 \\sim 4$.",
