Universal Pion Freeze-out Phase-Space Density

Mostrar otras versiones (1)

Results on the pion freeze-out phase-space density in sulphur-nucleus, Pb-Pb and pion-proton collisions at CERN-SPS are presented. All heavy-ion reactions are consistent with the thermal Bose-Einstein distrtibution f=1/(exp(E/T)-1) at T~120 MeV, modified for expansion. Pion-proton data are also cons...

description Results on the pion freeze-out phase-space density in sulphur-nucleus, Pb-Pb and pion-proton collisions at CERN-SPS are presented. All heavy-ion reactions are consistent with the thermal Bose-Einstein distrtibution f=1/(exp(E/T)-1) at T~120 MeV, modified for expansion. Pion-proton data are also consistent with f, but at T~180 MeV.

All heavy-ion reactions are consistent with the thermal Bose-Einstein distribution ƒ = [exp( E/T ) − 1] −1 at T ∼ 120 MeV, modified for radial expansion. π-p data are also consistent with ƒ, but at T ∼ 180 MeV and without radial flow.hep-ph/9901230oai:cds.cern.ch:3757731999-01-06
