Abstract (english)

The contribution of instanton-induced effective interquark interactions to the baryon mass splittings is considered in the bag model. It is found that results are different from those obtained in the constituent quark model where the instanton effects are like those from one-gluon exchange. This is because, in the context of the bag model calculation, the one-body instanton-induced interaction has to be included.
