In heavy ion collisions a relativistic description is essential in order to achieve correct results, since relativistic effects, such as time dilation or length contraction, grow with increasing velocities.
At low beam energies hadron transport approaches are successfully employed to describe the dynamical evolution of heavy ion reactions. Even though the underlying Boltzmann equation is covariant, it is known, that the geometric collision criterion used in the numerical solution introduces non-local interactions. In this work, a newly developed transport approach, SMASH (Simulating Many Accelerated Strongly-interacting Hadrons) is tested for Lorentz invariance.
The collision rates of these transport calculations in different observational reference frames are compared in order to observe a possible frame dependency in the calculation. A procedure of performing Lorentz boosts to different frames as well as the results for several initial and boundary conditions is presented. From these results, conclusions about the conditions under which the calculations are Lorentz invariant can be drawn.
