Holographic Walking Technicolor from D-branes

Understand

We investigate a model of dynamical electroweak symmetry breaking via a dual gravitational description.

• The gravity dual is obtained by embedding a D7 - anti-D7 pair of branes into a type IIB background that is dual to a walking gauge theory.
• We develop further a previous study of this model.
• In particular, we show that there is a nontrivial relation that needs to be satisfied in order for axial-vector modes to exist.
