JAM is a Hadronic Cascade Model, which explicitly treats all established hadronic states including resonances
with explicit spin and isospin as well as their anti-particles. We have
parameterized all Hadron-Hadron Cross Sections, based on Resonance Model and String Model by fitting the available experimental data.
