Decay of a scalar $\sigma$-meson near the critical end-point in the PNJL model

A. V. Friesen, Yu. L. Kalinovsky, V. D. Toneev

Properties of a scalar $\sigma$-meson are investigated in the two-flavor Nambu-Jona-Lasinio model with the Polyakov loop. Model analysis of the phase diagram of strong interacting matte…
