Chronos said:. This potentially explains a longstanding mystery - why the universe became dominated by matter while anti matter graciously stepped aside.
CP violation refers to the difference in behavior between particles and their antiparticles under the combined operation of charge conjugation (C) and parity (P). In the baryon sector, CP violation is the phenomenon in which certain baryons (particles made up of three quarks) decay differently than their antiparticles.
Scientists use a parameter called the CP-violating phase angle (ϕ) to measure CP violation in the baryon sector. This angle is calculated by comparing the decay rates of baryons and anti-baryons in a specific decay process.
The strongest evidence for CP violation in the baryon sector comes from experiments at the Large Hadron Collider (LHC). These experiments have observed a difference in the decay rates of particles and antiparticles in certain baryon decays, indicating the presence of CP violation.
Studying CP violation in the baryon sector can help scientists understand the fundamental nature of matter and the origins of the universe. It can also provide insights into the asymmetry between matter and antimatter in the universe, which is still a major mystery in physics.
If CP violation is proven to exist in the baryon sector, it would provide strong evidence for physics beyond the Standard Model. It could also lead to the discovery of new particles or interactions that could help explain the asymmetry between matter and antimatter in the universe.
