Exotic mesonIn 1997, the discovery of a new sub-atomic particle was announced, called the "exotic meson." Scientists speculated that the exotic meson might comprise four quarks, unlike all other known particles, which have three. The research team included physicists at Brookhaven National Laboratory, Upton, N.Y., and other facilities in the U.S. and Russia.eb |
