Wikipedia
Tetraquark
A tetraquark, in particle physics, is an exotic meson composed of four valence quarks. A tetraquark state has long been suspected to be allowed by quantum chromodynamics, the modern theory of strong interactions. A tetraquark state is an example of an exotic hadron which lies outside the conventional quark model classification. A number of different types of tetraquark have been observed.

Tetraquark
A tetraquark, in particle physics, is a hypothetical meson composed of four valence quarks. In principle, a tetraquark state may be allowed in quantum chromodynamics, the modern theory of strong interactions. However, there has been no confirmed report of a tetraquark state to date. Any established tetraquark state would be an example of an exotic hadron which lies outside the quark model classification. In 2003 a particle temporarily called X, by the Belle experiment in Japan, was proposed to be a tetraquark candidate, as originally theorized. The name X is a temporary name, indicating that there are still some questions about its properties to be tested. The number following is the mass of the particle in MeV. In 2004, the DsJ state seen in Fermilab's SELEX was suggested as a possible tetraquark candidate. In 2009, Fermilab announced that they have discovered a particle temporarily called Y, which may also be a tetraquark. There are as well indications that the Y, discovered by Belle in 2007, could be a tetraquark state. In 2010, two physicists from DESY and a physicist from Quaid-i-Azam University re-analyzed former experimental data and announced that, in connection with the ϒ meson, a well-defined tetraquark resonance exists.
