Abstract

Transverse momentum distributions of both positive and negative charged particles produced in 200 GeV/ AMU heavy ion collisions are obtained with Magnetic-Interferometric-Emulsitn-Chamber by CERN-EMU05 experiments. The Transverse momentum (P_T) spectra at both central and target rapidity regions showed no anomalous enhancement of low P_T components over a conventional, single exponential function with slope values ranging from 160 to 200 MeV/c. Charge-sign clustering test were tested. G-test were applied for some high multiplicity event. Charge-sign clustering does not exceed that from a random coincidence.
