Meson Decay

Meson decay refers to the process where mesons, which are subatomic particles composed of a quark and an antiquark, transform into lighter particles through the weak or strong nuclear force. This decay happens spontaneously over extremely short timescales, resulting in the meson breaking apart into other particles such as pions, muons, or photons. The specifics of the decay depend on the type of meson and the fundamental interactions involved. Studying meson decay helps scientists understand fundamental forces and the behavior of matter at the smallest scales.
