Candidates
There are several exotic hadron candidates:
- X(3872) – Discovered by the Belle detector at KEK in Japan, this particle has been variously hypothesized to be diquark or a mesonic molecule.
- Y(3940) – This particle fails to fit into the Charmonium spectrum predicted by theorists.
- Y(4140) – Discovered at Fermilab in March 2009
- Y(4260) – Discovered by the BaBar detector at SLAC in Menlo Park, California this particle is hypothesized to be made up of a gluon bound to a quark and antiquark.

Famous quotes containing the word candidates:
“In the past, it seemed to make sense for a sportswriter on sabbatical from the playpen to attend the quadrennial hawgkilling when Presidential candidates are chosen, to observe and report upon politicians at play. After all, national conventions are games of a sort, and sports offers few spectacles richer in low comedy.”
—Walter Wellesley (Red)
“Which one of the three candidates would you want your daughter to marry?”
—H. Ross Perot (b. 1930)
“Is it not manifest that our academic institutions should have a wider scope; that they should not be timid and keep the ruts of the last generation, but that wise men thinking for themselves and heartily seeking the good of mankind, and counting the cost of innovation, should dare to arouse the young to a just and heroic life; that the moral nature should be addressed in the school-room, and children should be treated as the high-born candidates of truth and virtue?”
—Ralph Waldo Emerson (1803–1882)
