    "abstract": "The covariant and non-covariant Quantum Molecular Dynamics models are applied\nto investigate possible relativistic effects in heavy ion collisions at SIS\nenergies. These relativistic effects which arise due to the full covariant\ntreatment of the dynamics are studied at bombarding energies E$_{lab.}$ = 50,\n250, 500, 750, 1000, 1250, 1500, 1750 and 2000 MeV/nucl.. A wide range of the\nimpact parameter from b = 0 fm to b = 10 fm is also considered. In the present\nstudy, five systems $^{12}$C-$^{12}$C, $^{16}$O-$^{16}$O, $^{20}$Ne-$^{20}$Ne,\n$^{28}$Si-$^{28}$Si and $^{40}$Ca-$^{40}$Ca are investigated. The full\ncovariant treatment at low energies shows quite good agreement with the\ncorresponding non-covariant approach whereas at higher energies it shows less\nstopping and hence less thermal equilibrium as compared to the non-covariant\napproach. The collisions dynamics is less affected. The density using RQMD\nrises and drops faster than with QMD. The relativistic effects show some\ninfluence on the resonance matter production. Overall, the relativistic effects\nat SIS energies ($\\leq$ 2000 MeV/nucl.) are less significant.",
