Small Elements in Fermion Mass Matrices and Anomalous Dipole Moments

Abstract

Assuming the small entries in the mass matrices are produced by fermion-scalar loops, we calculate the anomalous dipole moments of the leptons and quarks. The top quark appears in all the loops as the mass seed. When comparing the results with experimental data, including electric and magnetic dipole moments, and radiative transition rates, we obtain the mass limits which are typically larger than .1 TeV for the relevant neutral scalars, and 70 TeV for the relevant lepto-quarks. We then discuss the $P-\bar{P}$ mixing with a toy model. Rates of the known mixings require the masses of some neutral scalars to be large.
