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…

A Real CAM-Do Attitude

Photosynthesis, the method plants use to convert energy from the sun into food, is a ubiquitous process many people learn about in elementary school. Almost all plants use photosynthesis to gather energy and stay alive. Not all photosynthetic processes are the same, though. In recent years, researchers have grown increasingly…

Experts Converge on ORNL for US-Japan Fusion Workshop

For nearly 40 years the United States and Japan have collaborated on making the dream of limitless clean energy a reality. In 1980 the two countries created the US-Japan Joint Institute for Fusion Theory (JIFT) to formalize this collaboration. Since that time researchers from both countries have organized workshops to…

Physics Researchers Question Calcium 52’s Magic

The image above shows the chain of the studied calcium isotopes. The “doubly magic” isotopes with mass numbers 40 (Ca-40) and 48 (Ca-48) exhibit equal charge radii. The first measurement of the charge radius in Ca-52 yielded an unexpectedly large result. For decades nuclear physicists have tried to learn more…
