Electroweak Symmetry Breaking from Gauge/Gravity Duality Speaker(s): Lilia Anguelova
Abstract: We utilize the tools of the gauge/gravity correspondence in order to investigate electroweak symmetry breaking (EWSB). For quite some time now, a walking technicolor sector has been viewed by phenomenologists as a very promising alternative to the Higgs boson. Unfortunately however, no precise computations have been possible since in the technicolor gauge theory EWSB is due to strongcoupling dynamics. Using recent developments in the gauge/gravity duality, we construct a gravity dual of a walking technicolor model and aim to compute the PeskinTakeuchi Sparameter, which is an observable that can distinguish between a Higgs and a technicolor sector.
