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…

Jefferson Lab–NVIDIA Collaboration Uses Titan to Boost Subatomic Particle Research

Scientists are only beginning to understand the laws that govern the atomic world. Before the 1950s the electrons, neutrons, and protons comprising atoms were the smallest confirmed units of matter. With advancements in experimental and theoretical techniques in recent decades, though, researchers now try to understand even smaller particles at…
