Abstract

We investigate a dynamical mechanism to generate fermion mass in the Randall–Sundrum background. We consider four-fermion interaction models where the fermion field propagates in an extra-dimension, i.e. the bulk four-fermion interaction model. It is assumed that two types of fermions with opposite parity exist in the bulk. We show that electroweak-scale mass is dynamically generated for a specific fermion–antifermion condensation, even if all the scale parameters in the Lagrangian are set to the Planck scale.
