Forced canonical thermalization in a hadronic transport approach at high density

Understand

Hadronic transport approaches based on an effective solution of the relativistic Boltzmann equation are widely applied for the dynamical description of heavy ion reactions at low beam energies.

• At high densities, the assumption of binary interactions often used in hadronic transport approaches may not be applicable anymore.
• Therefore, we effectively simulate the high-density regime using the local forced canonical thermalization.
• This framework provides the opportunity to interpolate in a dynamical way between two different limits of kinetic theory: the dilute gas approximation and the ideal fluid case.
