Exploring nucleon-nucleon collisions and clusterization within the antisymmetrized molecular dynamics transport model by means of a Bayesian analysis on a dataset from the FAZIA setup

초록

The in-medium nucleon-nucleon cross section and the cluster production are key ingredients in transport models for heavy-ion collisions. They have been constrained by the comparison of predictions of the AMD transport model to experimental data of 20Ne + 12C at 50 MeV/nucleon [C. Frosin et al., Phys. Rev. C 107, 044614 (2023)], tuning the related parameters in the framework of a Bayesian inference. Experimental data have been collected with four blocks of the FAZIA setup. A large dataset of observables has been included in the analysis. The prior distribution of the examined parameters was chosen on the basis of the existing literature. The posterior distribution indicates a trend towards a larger number of collisions per event with respect to the previously used simulations.
