Rapidity Variation of Thermal Parameters at SPS and RHIC

Abstract

The rapidity dependence of the chemical freeze-out thermal parameters $T$ and ${\mu }_B$ are determined at the highest RHIC and SPS energies. These show a systematic behavior towards an increase in ${\mu }_B$ away from mid-rapidity and a corresponding decrease in the temperature $T$.
