Oblique corrections from Higgsless models in warped space

We calculate the tree-level oblique corrections to electroweak precision observables generated in Higgless models of electroweak symmetry breaking with a 5D SU(2)L×SU(2)R×U(1)_B-L gauge group on a warped background. In the absence of brane induced kinetic terms (and equal left and right gauge couplings) we find the S parameter to be ~1.15, while T~U~0, as in technicolor theories. Planck brane induced kinetic terms and unequal left-right couplings can lower S, however for sufficiently low values of S tree-level unitarity will be lost. A kinetic term localized on the TeV brane for SU(2)D will generically increase S, however an induced kinetic term for U(1)_B-L on the TeV brane will lower S. With an appropriate choice of the value of this induced kinetic term S~0 can be achieved. In this case the mass of the lowest Z^' mode will be lowered to about 300 GeV.
