Dynamical fermion masses under the influence of Kaluza-Klein fermions in extra dimensions
Hiroyuki Abe, Hironori Miguchi, Taizo Muta
Abstract
The dynamical fermion mass generation in the 4-dimensional brane is discussed in a model with 5-dimensional Kaluza-Klein fermions in interaction with 4-dimensional fermions. It is found that the dynamical fermion masses are generated beyond the critical radius of the compactified extra dimensional space and may be made small compared with masses of the Kaluza-Klein modes.
