Technicolor Walks at the LHC

We analyze the potential of the Large Hadron Collider (LHC) to observe signatures of phenomenologically viable walking technicolor models. We study and compare the Drell-Yan and vector boson fusion mechanisms for the production of composite heavy vectors. We find that the heavy vectors are most easily produced and detected via the Drell-Yan processes. The composite Higgs phenomenology is also studied. If technicolor walks at the LHC, its footprints will be visible and our analysis will help in uncovering them.

Holographic models for QCD in the Veneziano limit

A bstractWe construct a class of bottom-up holographic models with physics comparable to the one expected from QCD in the Veneziano limit of large Nf and Nc with fixed

A holographic quantum Hall model at integer filling

The models capture the holographic dynamics of the dilaton (dual to the YM coupling) and a tachyon (dual to the chiral condensate), and are parametrized by the real parameter x, which can take values within the range

Unitarity in Technicolor

. We analyze the saddle point solutions, and draw the phase diagram at zero temperature and density. The back-reaction of flavor on the glue is fully included. We find the conformal window for x ≥ xc, and the QCD-like phase with chiral symmetry breaking at x < xc, where the critical value xc lies close to four. We also find Miransky scaling as x → xc as well as Efimov-like saddle points. By calculating the holographic β-functions, we demonstrate the “walking” behavior of the coupling in the region near and below xc.

V-QCD: Spectra, the dilaton and the S-parameter

A bstractHolographic models in the T = 0 universality class of QCD in the limit of large number Nc of colors and Nf massless fermion flavors, but constant ratio xf = Nf/Nc, are analyzed at finite temperature. The models contain a 5-dimensional metric and two scalars, a dilaton sourcing TrF2 and a tachyon dual to
