High $p_{T}$ charged-pion production in Pb-Au collisions at 158 AGeV/c

The CERES/Na45 experiment at CERN SPS measured transverse momentum spectra ofcharged-pions in the range 1<pt<4GeV/c near mid-rapidity in 158 AGeV/c Pb-Aucollisions. The invariant transverse momentum spectra are exponential over theentire observed range. The average inverse slope is 245+/- 5MeV...

description The CERES/Na45 experiment at CERN SPS measured transverse momentum spectra ofcharged-pions in the range 1<pt<4GeV/c near mid-rapidity in 158 AGeV/c Pb-Aucollisions. The invariant transverse momentum spectra are exponential over theentire observed range. The average inverse slope is 245+/- 5MeV/c, it shows a2.4 0ncrease with centrality of the collision over the 35most centralfraction of the cross section. The pi-/pi+ ratio is constant at 1.028+/-0.005over the pt interval measured.
