Thermal hadron production in high energy collisions
It is shown that hadron abundances in high energy ee, pp and pp̄ collisions, calculated by assuming that particles originate in hadron gas fireballs at thermal and partial chemical equilibrium, are in very good agreement with the data. The freeze-out temperature of the hadron gas fireballs turns out to be nearly constant over a large center of mass energy range and not dependent on the initial c...
متن کاملThermal Hadron Production in High Energy Heavy Ion Collisions
We provide a method to test if hadrons produced in high energy heavy ion collisions were emitted at freeze-out from an equilibrium hadron gas. Our considerations are based on an ideal gas at fixed temperature Tf , baryon number density nB, and vanishing total strangeness. The constituents of this gas are all hadron resonances up to a mass of 2 GeV; they are taken to decay according to the exper...
متن کاملTHERMAL HADRON PRODUCTION IN Si-Au COLLISIONS
The most abundantly produced hadron species in Si−Au collisions at the BNL-AGS (nucleons, pions, kaons, antikaons and hyperons) are shown to be in accord with emission from a thermal resonance gas source of temperature T ≃ 110 MeV and baryochemical potential μB ≃ 540 MeV, corresponding to about 1/3 standard nuclear density. Our analysis takes the isopin asymmetry of the initial state fully into...
متن کاملThermal hadron production in relativistic nuclear collisions
We present the status of the description of hadron production in central nucleus-nucleus collisions within the statistical model . Extending previous studies by inclusion of very high-mass resonances (m> 2 GeV), and the upto-now neglected scalar σ meson leads to an improved description of the data. In particular, the hitherto poorly reproduced energy dependence of theK/π ratio at SPS energies (...
متن کاملPhoton + Hadron Production in High Energy Deuteron (Proton)-Nucleus Collisions
We apply the Color Glass Condensate formalism to photon + hadron production cross section in high energy deuteron (proton)-gold collisions at RHIC. We investigate the dependence of the production cross section on the angle between the produced hadron and photon for various rapidities and transverse momenta. It is shown that the angular correlation between the produced hadron and photon is a sen...
