FRIGA, a new approach to identify isotopes and hypernuclei in n-body transport models

We present a new algorithm to identify fragments in computer simulations of relativistic heavy-ion collisions. It is based on the simulated annealing technique and can be applied to n-body transport models like the Quantum Molecular Dynamics. This new approach is able to predict isotope yields as well as hypernucleus production. In order to illustrate its predicting power, we confront this new method to experimental data, and show the sensitivity on the parameters which govern the cluster formation
