Universal pion freeze-out phase-space density

Mostrar otras versiones (1)

Results on the pion phase-space density at freeze-out in sulphur- nucleus. Pb-Pb and pi -p collisions at the CERN SPS are presented. All heavy-ion reactions are consistent with the thermal Bose-Einstein distribution f=[exp(E/T)-1]/sup -1/ at T~120 MeV, modified for radial expansion. pi -p data are a...

description Results on the pion phase-space density at freeze-out in sulphur- nucleus. Pb-Pb and pi -p collisions at the CERN SPS are presented. All heavy-ion reactions are consistent with the thermal Bose-Einstein distribution f=[exp(E/T)-1]/sup -1/ at T~120 MeV, modified for radial expansion. pi -p data are also consistent with f, but at T~180 MeV and without radial flow. (18 refs).
