Maximum entropy kinetic matching conditions for heavy-ion collisions

Coupling hadronic kinetic theory models to fluid dynamics in phenomenological studies of heavy ion collisions requires a prescription for ``particlization''. Existing particlization are based on implicit or explicit assumptions about the microscopic degrees freedom that go beyond information provided by preceding dynamical history. We propose an alternative which uses only macroscopic hydrodynamic output. This method follows directly from connections between and statistical mechanics.
