Mjesto: IRB, I krilo, soba 204Sažetak: - The relationship between the scalar-isoscalar spectral function of strong matter and the second Riemann sheet pole in the same channel is analyzed in an effective linear sigma-model. An expansion in the number of the Goldstone bosons is applied to leading order. A generic scenario is suggested for the temperature/baryon density driven evolution of the pole location. In an extended temperature range closely related to the characteristic parts of the pole trajectory one observes the enhancement of the spectral function at the two-pion treshold.
