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

In particle physics, B mesons are mesons composed of a bottom antiquark and either an up ( B+ ), down ( B0 ), strange ( B0 s) or charm quark ( B+ c)....

physics, exotic mesons are mesons that have quantum numbers not possible in the quark model; some proposals for non-standard quark model mesons could be: glueballs...

particle physics, the phi meson or ϕ meson is a vector meson formed of a strange quark and a strange antiquark. It was the ϕ meson's unusual propensity to...

the charm quark was first seen in the J/Psi meson ( J/ψ ) in 1974, and the bottom quark in the upsilon meson ( ϒ ) in 1977. The top quark (the last and...

pions and omega mesons, the rho meson carries the nuclear force within the atomic nucleus. After the pions and kaons, the rho mesons are the lightest...

physics, a pseudoscalar meson is a meson with total spin 0 and odd parity (usually notated as JP = 0− ). Pseudoscalar mesons are commonly seen in proton-proton...
