Recent progress on light scalar mesons

This is a brief account of the recent developments on the determination of the mass and widths of the much debated scalar mesons, paying particular attention to the causes of major revision of the σ or f_0(500) meson in the last edition of the Review of Particle Physics, which has finally acknowledg...
