Collective expansion in high energy heavy ion collisions

Transverse mass spectra of pions, kaons, and protons from the symmetric heavy-ion collisions 200A$\cdot$GeV S+S and 158A$\cdot$GeV Pb+Pb, measured in the NA44 focusing spectrometer at CERN, are presented. The mass dependence of the slope parameters provides evidence of collective transverse flow %BV...

Descripción
Sumario:Transverse mass spectra of pions, kaons, and protons from the symmetric heavy-ion collisions 200A$\cdot$GeV S+S and 158A$\cdot$GeV Pb+Pb, measured in the NA44 focusing spectrometer at CERN, are presented. The mass dependence of the slope parameters provides evidence of collective transverse flow %BVJ from expansion of the system in heavy--ion induced central collisions.
