Examples
-
The existence of a new form of matter called a tetraquark has been given further support by the re-analysis of an experiment that has baffled particle physicists for the past two years.
-
One of these is the tetraquark, which comprises two quarks and two antiquarks.
-
One possible explanation is that the electron-positron collisions tuned to form Y (5S) may have actually been producing a different particle altogether - a tetraquark meson Y
-
The existence of the tetraquark - a particle made of four quarks - looks increasingly likely with a fresh sighting in a Japanese particle accelerator

b (10890) tetraquark meson comprising up (u) and bottom (b) quarks and their respective antiquarks.
-
b (10890), a tetraquark meson formed of an up flavour "diquark" (quark-antiquark pair) and a bottom flavour diquark, is very close in mass to Y (5S).
