Dynamical Low-Mass Fermion Generation in Randall-Sundrum Background
It is investigated that a dynamical mechanism to generate a low mass fermion
in Randall-Sundrum (RS) background. We consider a five-dimensional four-
fermion interaction model with two kinds of bulk fermion fields and take all
the mass scale in the five-dimensional spacetime at the Planck scale.
Evaluating the effective potential of the induced four-dimensional model, I
calculate the dynamically generated fermion mass. It is shown that dynamical
symmetry breaking takes place and one of the fermion mass is generated at the
electroweak scale in four dimensions.Comment: 7pages, 3 figures, Talk given at the 2002 International Workshop on
