Pion

A pion is a type of subatomic particle found in the field of particle physics. It comes in three varieties: positively charged, negatively charged, and neutral. Pions play a crucial role in mediating the strong force, which holds atomic nuclei together. This force is essential for the stability of atoms. Pions are relatively short-lived and are produced in high-energy environments, such as in particle collisions. Their study helps scientists understand the fundamental forces that govern matter and the interactions between particles in the universe.
