Constraints on a preonic model for family replication from the anomalous magnetic moment of leptons

The additional contributions to the anomalous magnetic moment of the muon and the electron ((g-2)l) in a recently suggested preonic model are considered. It is shown that the parameters in this model are severely restricted when the constraints coming from this analysis are combined with those obtained from the considerations of the quark-lepton mass matrices and mixing angles.
