Dual technicolor with hidden local symmetry

Abstract

We consider a dual description of the technicolor-like gauge theory within the D4/D8 brane configuration with varying confinement and elecroweak symmetry breaking scales. Constructing an effective truncated model valid below a certain cut-off, we identify the particle spectrum with Kaluza-Klein modes of the model in a manner consistent with the hidden local symmetry. Integrating out heavy states, we find that the low-energy action receives nontrivial corrections stemming from the mixing between Standard Model and heavy gauge bosons which results in reduction of oblique parameters.
