ETAMESON

Eta meson

The eta and eta prime meson are mesons made of a mixture of up, down and strange quarks and their antiquarks. The charmed eta meson and bottom eta meson are forms of quarkonium; they have the same spin and parity as the light eta but are made of charm quarks and bottom quarks respectively. The top quark is too heavy to form a similar meson, due to its very fast decay.
