Summary
I plan to give a brief review on Higgsless theories of
electroweak symmetry breaking.
In this class of models, electroweak symmetry is assumed to be
broken through the
boundary condition imposed on an interval extra dimension.
Unitarity of the
longitudinal W boson scattering can be satisfied thanks to the
exchange of spin-1
Kaluza-Klein particles. We show that low energy Higgsless
phenomenologies can be
well described by a four dimensional effective theory called
"three-site Higgsless
model", in which we compute Peskin-Takeuchi S and T parameters
including one-loop
radiative corrections. We also compute
flavor-changing-neutral-current constraints in
this model.
