abstract:In particle physics, a rho meson is a short-lived hadronic particle that is an isospin triplet whose three states are denoted as , and . After the pions and kaons, the rho mesons are the lightest strongly interacting particle with a mass of roughly for all three states.
Rho meson gets quite much attention and is expected to carry information about thecentralfireball formed in the heavy ioncollision, becauseitslifetime is shorter than that of the fireball.
