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 "Strong Coupling Gauge Theories and Effective Field Theories" (SCGT 02), Nagoya, Japan, 10-13 December 200
