Description
We study the low-energy effects of a 4 fermion operator in a 5-dimensional
space-time with a single compactified extra dimension. Quantum effects due to
fermion loops renormalize the theory, and lead to dynamical scalar degrees of
freedom which can be considered to be bound states of 5-dimensional fermions.
For critical values of the 4-fermion coupling, these bound states can condense,
breaking the chiral symmetries of the theory. We consider application to extra-
dimensional models of electroweak symmetry breaking.
