The origin of mass hierarchies for different systems of fundamental interactions; in particular, whether the W/sub L/- W/sub R/ mass splitting, and the fermion mass hierarchy can be of radiative origin is studied. Within the elementary Higgs field approach the author shows that the desired solution for the mass matrix emerges as an interplay between certain hard terms of the Higgs potential, which respect the global symmetry SU(4)/sub L/ x SU(4)/sub R/ of four flavors, and the soft terms, which respect the gauge symmetry SU(2)/sub L//sup e + ..mu../ x SU(2)/sub R//sup e + ..mu../. Some of the soft terms of nonperturbative origin, while some are induced radiatively. The proper inter-and intra-family hierarchy as well as the desired Cabibbo mixing angles can be reproduced, but the results depends on the parameters of the Higgs potential.
