Physicists at Brookhaven Lab used the STAR detector to study high-energy particle collisions. They found that gluons, tiny particles holding quarks together, might play a key role in carrying baryon number. This challenges our current understanding of protons.
Protons are tiny building blocks of atoms. They have three main parts: quarks. Scientists thought these quarks carried a property called baryon number. But now, new research suggests that gluons might be responsible for carrying this number.
The STAR detector at Brookhaven Lab in the US studied high-energy particle collisions. The team found that when protons collide, the total number of baryons remains unchanged. This is known as conservation of baryon number. It's a fundamental principle that helps explain why matter exists in the universe.
The new findings come from data collected by the STAR collaboration between 2000 and 2026. The team used different types of collisions to test their theory. They found that the baryon number is not carried solely by individual quarks, but rather by gluons arranged in a special configuration.
This discovery could change what we know about protons. It might also help us understand why matter exists and why it's stable.
Why It Matters
Understanding how protons work can help us better comprehend the universe. This research could lead to new discoveries and insights into the fundamental laws of physics.
