Phi meson production cross sections in pion-baryon and baryon-baryon interactions Academic Article

abstract

• Phi meson production in pion-baryon and baryon-baryon interactions near the production threshold is studied in a boson-exchange model. Parameters in this model are either taken from the Bonn model for the nucleon-nucleon potential or determined from the measured phi meson decay width and the experimental data for the reactions - pn and pppp. The isospin-averaged cross sections for the reactions NN, N, NNNN, which are needed in transport models to study phi meson production in heavy-ion collisions at subthreshold energies, have been evaluated. For the reactions NNN and NN, which become singular when the exchanged pion is on-shell, the Peierls method is used to calculate their cross sections. We find that the cross section for the reaction NN is much larger than the other cross sections. 1997 Elsevier Science B.V.
