Color Evaporation

1
Color Evaporation

• This theory attempts to account for rapidity gaps
  in diffractive events without resorting to the
  use of a Pomeron
• Model has been successfully applied to onium
  production (charmonium, J/psi)
• Proposes that allowing soft color
  (non-perturbative) interactions can change the
  hadronization process such that color is bleached
  out and rapidity gaps appear
• Soft Color shows same exponential t-dependence as
  Ingelman-Schlein due to primordial kT of the
  partons
• Suggests a formation rate of gaps in gluon-gluon
  sub processes which is less than or equal to the
  formation rate in quark-quark sub processes
