Query: Baryon spectra with instanton induced forces   Except the vibrational excitations of $K$ and $K^*$ mesons, the main features
of spectra of mesons composed of quarks $u$, $d$, and $s$ can be quite well
described by a semirelativistic potential model including instanton induced
forces. The spectra of baryons composed of the same quarks is studied using the
same model. The results and the limitations of this approach are described.
Some possible improvements are suggested.
