B quarks are one of the six types of quarks in the Standard Model of particle physics. They have a charge of -1/3 and are heavier than up and down quarks. B quarks combine with other quarks to form particles called hadrons, such as B mesons and B baryons. B quarks play a significant role in the study of flavor physics and CP violation, which helps scientists understand the differences between matter and antimatter. Their interactions are crucial for exploring the fundamental forces that govern the universe.
