Scalar Mesons in a Relativistic Quark Model with Instanton-Induced Forces

E. Klempt, B. C. Metsch, C. R. Munz +1

In a relativistic quark model with linear confinement and an instanton-induced interaction which solves the $\eta$-${\eta }^{\prime }$ puzzle, scalar mesons are found as almost pure SU(3) flavor sta…
