Abstract:
The energy dependence of the total kaon production cross sections in baryon-baryon (N and Delta) collisionsare studied in the resonance model, which is a relativistic tree-level treatment. This study is the first attempt to complete a systematic consistent investigation of the elementary kaon production reactions for both the pion-baryon and baryon-baryon reactions. Our model suggests that the magnitudes of the isospin-averaged total cross sections for the NN-->NYK and Delta N-->NYK (Y=Lambda or Sigma) reactions are almost equal at energies up to about 200 MeV above threshold. However, the magnitudes for the Delta N reactions become about 6 times larger than those for the NN reactions at energies about 1 GeV above threshold. Furthermore, the magnitudes of the isospin-averaged total cross sections for the NN-->Delta YK reactions turn out to be comparable to those for the NN-->NYK reactions at NN invariant collision energies about 3.1 GeV, and about 5 to 10 times larger at NN invariant collision energies about 3.5 GeV. The microscopic cross-sections are parametrized in all isospin channels necessary for the transport model studies of kaon production in heavy-ion collisions. These cross sections are then applied in the relativistic transport model to study the sensitivity to the underlying elementary kaon production cross sections. [S0556-2813(99)03201-X].
