摘要：
Exotic mesons with quantum numbers of a hybrid ((q) over bar qg) such as J(PC) = 1(-+) are shown to exist as narrow resonant states in the large N-c limit of QCD. The width of these states is proportional to 1/N-c. Possible phenomenological implications for the world of N-c = 3 are discussed. (C) 1998 Elsevier Science B.V. All rights reserved.
