In recent years several Large-Scale Scientific Facilities (LSSF) for nuclear, hadronic, and particle physics have been upgraded and constructed in China.

University of Michigan physicists played a leading role in the discovery of a new particle, the Omega b baryon, which is an exotic relative of the proton.

New, higher precision data that could only have been gathered at the Department of Energy’s Thomas Jefferson National Accelerator Facility (Jefferson Lab) shows the Theta-plus pentaquark doesn’t appear in another place it was expected. This intriguing finding contradicts evidence previously presented by Jefferson Lab researchers that they had sighted a pentaquark, a particle built of five quarks.

The elusive subatomic particle called the pentaquark is up for grabs again.

DENVER -- An experiment expressly designed to detect ''pentaquarks'' confirms the existence of these exotic physics particles, researchers reported Sunday.The discovery involves tiny particles called quarks, the bricks and mortar of particles inside atoms.
