Where are mesons found? (1) Cosmic rays (2) X-rays (3) Gamma rays (4) Laser beam
by

1 Answer

Answer :

(1) Cosmic rays Explanation: Mesons are not produced by radioactive decay, but appear in nature only as short-lived products of very high-energy interactions in matter, between particles made of quarks. In cosmic ray interactions, for example, suchparticles are ordinary protons and neutrons. Mesons are hadronic subatomic particles composed of one quark and one anti-quark, bound together by the strong interaction.
