Hybrid Model

• First stage: Intra-nuclear cascade

  • Produces distribution of residue sizes and E*
  • Convert E* into temperature and percolation breaking probability p(T) = 1 - 2 G[3/2,0,B/T] / ¶pG = generalized incomplete gamma function, B = binding energy per nucleon

1 A GeV Au + C

• Second stage: Percolation model with lattice size = charge of residue

  • Produces fragments

• Total multiplicity = INC pre-equil.+percolation output
