Particlization with local event-by-event conservation laws

Understand

We present a sampling method for the transition from relativistic hydrodynamics to particle transport, commonly referred to as particlization, which preserves the local event-by-event conservation of energy, momentum, baryon number, strangeness, and electric charge.

• The proposed method is essential for studying fluctuations and correlations by means of stochastic hydrodynamics.
• It is also useful for studying small systems.
• The method is based on Metropolis sampling applied to particles within distinct patches of the hypersurface, where hydrodynamics and kinetic evolutions are matched.
