Vector mesons from AdS/TC to the LHC

Understand

With the use of the AdS/CFT dictionary, a five-dimensional effective description of dynamical electro-weak symmetry breaking with walking behavior is constructed.

• The minimal model contains only two new parameters, the confinement scale and the effective coupling of the new strong sector.
• This parameter space is restricted by the precision electro-weak constraints and by the requirement that the five-dimensional coupling be perturbative (corresponding to the large-N regime in four-dimensional language).
• The lightest observable new states are a set of four nearly degenerate spin-1 states with the same quantum numbers as the standard-model electro-weak gauge bosons, and masses in the few TeV range.
