Scientists have found "charge-parity (CP) violation", this discovery could help explain why there’s more matter than antimatter in the universe.

News in Detail

Scientists have discovered something new about matter and antimatter. Normally, matter and antimatter are supposed to behave like mirror images of each other. But sometimes, they don’t follow this rule, and that’s called charge-parity (CP) violation.

This discovery occurred at the Large Hadron Collider (LHC) near Geneva. Scientists found CP violation in a type of particle called baryons, which include protons and neutrons. Before this, they only knew about CP violation in another type of particle called mesons.

What are matter and antimatter?

Matter is everything we can see and touch, like planets, stars, and even our own body. Antimatter is like the opposite of matter. For example, if matter has a positive charge, antimatter has a negative charge.

When matter and antimatter meet, they destroy each other in a burst of energy. Scientists believe that after the Big Bang, there should have been equal amounts of matter and antimatter. But today, they only see matter. So, they’re trying to figure out why matter "won" over antimatter.

What is CP violation?

CP violation is when particles and their antimatter counterparts behave differently. Normally, particles and antiparticles are like perfect mirror images of each other. But in some cases, they break this symmetry. This difference is important because it might explain why there’s more matter than antimatter in the universe.

If CP violation didn’t exist, the universe would have equal amounts of matter and antimatter, and they would have destroyed each other completely.
