Abstract

We discuss a calculation of large-N_c masses of light scalar mesons from the QCD sum rules. Two methods based on the use of linear radial Regge trajectories are presented. We put a special emphasis on the appearance of pole near 0.5 GeV in the scalar-isoscalar channel which emerges in both methods and presumably corresponds to the scalar sigma meson.
