CMBE v05—Implementation of a toy-model for chaos analysis of relativistic nuclear collisions at the present BNL energies

In this paper we present a new version of Chaos Many-Body Engine (CMBE) Grossu et al. (2014) [1]. Inspired by the Mean Free Path concept, we implemented a new parameter, namely the “Mean Free Time”, which is defined as the mean time between one particle’s creation and its stimulated decay. This new parameter should be understood as an effect of the nuclear environment and, as opposed to the particle lifetime, it has the advantage of not being affected by the relativistic dilation. In [2] we presented a toy-model for chaos analysis of relativistic nuclear collisions at 4.5 A GeV/c (the SKM 200 collaboration). In this work, we extended our model to 200 A GeV (the maximum BNL energy).

Solution method: Relativistic many-body OOP engine, including a reactions module. Reasons for new version:1.Implementation of the “Mean Free Time” parameter;2.Implementation of a new example of use for relativistic nuclear collisions at present BNL energies. Summary of revisions:1.Implementation of a new parameter, namely the “Mean Free Time”, defined as the mean time between one particle’s creation and its stimulated decay. The Mean Free Time should be understood as an effect of the nuclear environment and, as opposed to the particle lifetime, it is measured in the observation system (not affected by the relativistic dilation). Following this purpose, a new tag (MeanFreeTime) was added in the “Particles” section of the specific XML reactions input file described in [2].2.Analysis ∖Chaos Analysis ∖Double ∖Other: Implementation of a, more reliable, fuzzy algorithm [3] for probability distribut
