New Five-Quarked Baryon State

Strong evidence for a new five-quark baryon state (known as a pentaquark) has been reported by a team of physicists known as the CLAS Collaboration working at the Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Virginia. Link

Surprise to physicists ? protons aren't always shaped like a basketball

When Gerald A. Miller first saw the experimental results from the Thomas Jefferson National Accelerator Facility, he was pretty sure they couldn’t be right. If they were, it meant that some long-held notions about the proton, a primary building block of atoms, were wrong. But in time, the findings proved to be right, and led physicists to the conclusion that protons aren’t always spherically shaped, like a basketball.
