The eta ( η ) and eta prime meson ( η′ ) are isosinglet mesons made of a mixture of up, down and strange quarks and their antiquarks. The charmed eta meson...

experiment at SLAC in 2008, and is the lightest particle containing a bottom and anti-bottom quark. Eta and eta prime mesons, a similar particle with light...

the most well studied and understood mesons, the decay properties of the pseudoscalar mesons, particularly of eta (η) and eta-prime (η′), are somewhat contradictory...

which suggests the mesons should be grouped into nonets (groups of nine). The eightfold way organizes eight of the lowest spin-0 mesons into an octet. They...

of classification. These include glueballs and hybrid mesons (mesons bound by excited gluons). Because mesons have an even number of quarks, they are also...

the 1980s. Scalar mesons are most often observed in proton-antiproton annihilation, radiative decays of vector mesons, and meson-meson scattering. The light...

between mesons and baryons is that mesons have integer spin (thus are bosons) while baryons are fermions (half-integer spin). Because mesons are bosons...

Bose–Einstein statistics and all have integer spins. Bosons may be either elementary, like photons and gluons, or composite, like mesons. According to the Standard...

Higgs boson) contributes to the phenomenon of mass. Other bosons, such as mesons, are composite particles made up of smaller constituents. Outside the realm...

mediated by particles known as mesons. The most familiar baryons are protons and neutrons, both of which contain three quarks, and for this reason they are...
