Query: A negative S parameter from Holographic Technicolor   We present a new class of 5D models, Holographic Technicolor, which fulfills
the basic requirements for a candidate of comprehensible 4D strong dynamics at
the electroweak scale. It is the first Technicolor-like model able to provide a
vanishing or even negative tree-level S parameter, avoiding any no-go theorem
on its sign. The model is described in the large-N regime. S is therefore
computable: possible corrections coming from boundary terms follow the 1/N
suppression, and generation of fermion masses and the S parameter issue do
split up. We investigate the model's 4D dual, probably walking Technicolor-like
with a large anomalous dimension.
