New Resonances and the Vector-Meson System

Under the assumption of exact $S{U}_{3}$ symmetry we investigate the force between two degenerate vectormeson octets due to the exchange of a vector, pseudoscalar, and scalar octet. It is found that many of the recently discovered particles may fit into this scheme as bound states. However, the model does not reproduce the well-known pseudoscalar and vector-meson octets which are its input, but suggests a second octet of each kind at higher mass. It also gives a ${0}^{+}$ and ${2}^{+}$ singlet and octet as well as a ${1}^{+}$ and a ${2}^{\ensuremath{-}}$ octet.
