EXTENDED TRANSVERSE-MOMENTUM ANALYSIS FOR INTERMEDIATE-ENERGY HEAVY-ION COLLISIONS

An extension of the transverse-momentum analysis of Danielewicz and Od yniec is proposed. This extension involves a consideration of baryonic p(T)-distribution widths in and out of the reaction plane. Calculatio ns within one- and two-fluid mean-field models show that such an analy sis allows us to extract more information on the nuclear equation of s tate and stopping power than the conventional one does. Different crit eria for selecting collision events (i.e. sorting them out according t o impact parameters) are also examined. Selections according to the ba ryonic multiplicity in the midrapidity region and the transversal-to-l ongitudinal energy ratio are found to be suitable for this purpose.
