Support for massless particles in Chaos Many-Body Engine simulations of nuclear collisions at relativistic energies
Following the goal of improving the relativistic nuclear collisions toy-model proposed in Grossu et al. (2014), we added support for massless particles in all “Many-Body”, “High Precision”, and “Reactions” modules of the Chaos Many-Body Engine application. In this context, we discuss a first CMBE–HI...

Summary: | Following the goal of improving the relativistic nuclear collisions toy-model proposed in Grossu et al. (2014), we added support for massless particles in all “Many-Body”, “High Precision”, and “Reactions” modules of the Chaos Many-Body Engine application. In this context, we discuss a first CMBE–HIJING comparative study on nuclear collisions at the maximum BNL energy. As a new high precision example of use, we implemented a 50 decimals precision simulation of a bound system composed by two massless particles with gravitational potential.
