K+/ pi + enhancement in heavy-ion collisions.
Kaon production from heavy-ion collisions is a topic of great interest. For heavy-ion collisions at =1 GeV/ nucleon, it has been shown that the kaon production probability is sensitive to the nuclear equation of state at high densities. ' At ultrarelativistic energy collisions available at the future heavy-ion collider, it has been argued that a kaon might carry the signature for the quark-gluo...
متن کاملChiral kaon dynamics in heavy ion collisions
The influence of the chiral mean field on the collective motion of kaons in relativistic heavy ion reactions at SIS energies is investigated. We consider three types of collective motion, i.e. the transverse flow, the out-of-plane flow (squeeze-out) and the radial flow. The kaon dynamics is thereby described with a relativistic mean field as it originates form chiral lagrangiens. For the K meso...
متن کاملK production in baryon-baryon and heavy-ion collisions
Kaon production cross sections in nucleon-nucleon, nucleon-delta and delta-delta interactions are studied in a boson exchange model. For the latter two interactions, the exchanged pion can be on-mass shell, only contributions due to a virtual pion are included via the Peierls method by taking into account the finite delta width. With these cross sections and also those for pion-baryon interacti...
متن کاملOrigin of subthreshold K production in heavy ion collisions
We investigate the origin of subthreshold K production in heavy ion collisions at intermediate energies. In particular we study the influence of the pion induced K creation processes. We find that this channel shows a strong dependence on the size of the system, i.e., the number of participating nucleons as well as on the incident energy of the reaction. In an energy region between 1–2 GeV/nucl...
متن کاملNear-threshold K+ production in heavy-ion collisions.
Within a hadronic transport model we study in detail contributions to kaon yields and momentum spectra from various baryon (resonance)-baryon (resonance) and πN interactions in heavy-ion collisions at beam energies near the free-space kaon production threshold. It is found that the finite lifetime of baryon resonances affects significantly the shape of kaon spectra, and the high energy parts of...
