Walking Dynamics from String Duals

A large class of solutions of the background equations for a specific system of D5-branes shows many of the properties of a walking theory. The gauge coupling is almost constant over an intermediate range of energies, the coupling is strong, the theory confines, a condensate forms. We study the Wilson loops and the spectrum of scalar glueballs in these backgrounds, finding quite surprising results. This model, and possibly its extensions, provide a suitable laboratory in which to study the (strongly coupled) properties of walking dynamics, which lies at the core of walking technicolor.
