Researchers Seek Sigma Meson on the Path to Heavier Hadrons

Schematic diagrams showing possible quark propagation channels in pion-pion scattering relevant for the sigma meson. Often, researchers aim for a distant horizon with respect to their research goals. When they get there, they plot their course for the next far-off landmark. Throughout the 20th century, researchers tried to understand the…
