We study the possible interpretation of the two exotic resonances J PC =1 −+ at 1400 and 1600 MeV, claimed to be observed by BNL, decaying, respectively, into ηπ, η′π, f 1 π and ρπ. These objects are interpreted as hybrid mesons, in the quark–gluon constituent model using a chromoharmonic confining potential. The quantum numbers J PC I G =1 −+ 1 ...
Hybrid ccg of quantum numbers 1 -- are considered in a quark model with constituent quarks and gluon. The lowest J P =1 - states may be built in two ways, l g =1 (gluon excited) corresponding to an angular momentum between the gluons and the cc system, while l cc =1 (quark excited) corresponds to an angular momentum between the c and the c. The lowest...
