Dynamical freeze-out in event-by-event hydrodynamics

Holopainen, Hannu, Huovinen, Pasi

Understand

In hydrodynamical modeling of the ultrarelativistic heavy-ion collisions the freeze-out is typically performed at a constant temperature or density.

  • In this work we apply a dynamical freeze-out criterion, which compares the hydrodynamical expansion rate with the pion scattering rate.
  • Recently many calculations have been done using event-by-event hydrodynamics where the initial density profile fluctuates from event to event.
  • In these event-by-event calculations the expansion rate fluctuates strongly as well, and thus it is interesting to check how the dynamical freeze-out changes hadron distributions with respect to the constant temperature freeze-out.
