FRIGA, a new approach to identify isotopes and hypernuclei in $\eta$-body transport models

We present a new approach to identify fragments using computer simulations of relativistic heavy ion collisions. It is based on the simulated annealing technique and can be applied to n-body transport models such as 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 with experimental data and show the sensitivity to the parameters which govern cluster formation.
