ETA-MESONS WITH INERT COMPONENTS

It is assumed that the (549) and (958) mesons are each composed of a nonstrange-quark part, a strange-quark part, and an inert" part that interacts weakly with mesons. This type of structure was suggested previously by the author on the basis of self-consistency conditions postulated by Odorico. Various experimental results on hadronic processes and electromagnetic decay rates are used to analyze the and wave functions. The results are compared with the predictions that follow from the Odorico postulate. It is suggested that the inert component is a gluon bound state. It is predicted that a third pseudoscalar meson with mass less than 2 GeV/c2 exists; this meson should be produced copiously in -p and K-p collisions at sufficiently high energy. © 1978 The American Physical Society."
