B Physics is a branch of particle physics that studies B mesons, which are particles made up of a bottom quark and either an up or down quark. These mesons are important for understanding the behavior of matter and antimatter, particularly in the context of CP violation, which helps explain why the universe is predominantly composed of matter. Researchers in B Physics conduct experiments at particle accelerators, such as the Large Hadron Collider or the B Factory, to observe the decay processes of B mesons. By analyzing these decays, scientists can test the predictions of the Standard Model of particle physics and explore potential new physics beyond it.
