One-, two- and three-particle hadron spectra - Recent results from CERN/SPS experiment NA44

摘要

Recent results of analyses on hadron spectra from the focusing spectrometer experiment NA44 are presented. One-, two- and three-particle hadron spectra in the mid-rapidity region at CERN/SPS energy have been measured. The m(T) inverse-slopes of proton and anti-proton in collision systems from p+A to Pbi-Pb are discussed. Spectra of deuteron, triton and anti-deuteron are presented, and the flow effect on the composite particle spectra are discussed. The two-particle interferometry analysis is made for the pi(+/-)pi(+/-) and K+K+ correlations in the central Pb+Pb collisions, and the dependences of interferometric parameters on the transverse mass and the multiplicity are discussed.
