B Mesons

B mesons are subatomic particles made up of a pair of quarks: one is a bottom quark and the other can be either an up, down, strange, or charm quark. They belong to a family of particles called mesons, which are involved in the strong force that binds protons and neutrons in atomic nuclei. B mesons are important in studying the nature of matter and antimatter, particularly in tests of the Standard Model of particle physics. Their behavior, including how they decay, helps physicists understand fundamental principles and the universe's evolution.
