Elementary particle physics reflects the human quest to understand the basic building blocks of nature and the rules that govern the physical world. This quest has led not only to critical scientific ...

Glueball confirmed: China's BESIII collaboration announced Aug. 5, 2026 that particle X(2370) is the first experimentally ...

For decades, a puzzling discrepancy involving a tiny subatomic particle called the muon fueled speculation that physicists might be on the verge of discovering an entirely new force of nature. Now, an ...

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

A “muon shot” aims to study the basic forces of the cosmos. But meager federal budgets could limit its ambitions. By Dennis Overbye and Katrina Miller See more of our coverage in your search ...

Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

A quirky type of subatomic particle known as the charm meson has the seemingly magical ability to switch states between matter and antimatter (and back again), according to the team of over 1,000 ...

At every moment, subatomic particles stream in unfathomable numbers through your body. Each second, about 100 billion neutrinos from the sun pass through your thumbnail, and you’re bathed in a rain of ...
