Description

The correlation between dilepton yields and pion multiplicities in the baryon-poor central region produced in ultra-relativistic nucleus-nucleus collisions is analyzed within a hydrodynamical framework. A 'cut-in' in the correlation function is predicted as signal of the deconfinement transition. Transverse flow effects, finite hadronization times of the deconfined matter and realistic initial matter distributions enhance this signal. (orig.)
