ρ Meson

The ρ (rho) meson is a type of subatomic particle, specifically a meson, composed of a quark and an antiquark. It acts as a carrier of the strong nuclear force within atomic nuclei, helping hold protons and neutrons together. The ρ meson is very short-lived and exists only briefly before transforming into other particles. It plays a crucial role in understanding the interactions between quarks and the behavior of nuclear matter. Studying the ρ meson helps physicists explore the fundamental forces and the structure of matter at the most microscopic level.
