- In
particle physics, a
tetraquark is an
exotic meson composed of four
valence quarks. A
tetraquark state has long been
suspected to be
allowed by quantum...
- The double-charm
tetraquark (T+ cc, ccud) is a type of long-lived
tetraquark that was
discovered in 2021 in the LHCb
experiment conducted at the Large...
-
glueballs or
gluonium Glueballs have no
valence quarks at all.
tetraquarks Tetraquarks have two
valence quark–antiquark pairs.

- pentaquarks,
containing five
valence quarks, are
exotic baryons,
while tetraquarks (four
valence quarks) and
hexaquarks (six quarks,

- more than
three valence quarks, have been
discovered in
recent years. A

named the Z(4430)−, was
discovered in 2007 by...

other exotic particle candidates such as a
