Title: Relaxation of the Composite Higgs Little Hierarchy
Host: Verhaaren
Room: 432
Abstract: In this talk, I will detail some recent work to implement the relaxation mechanism in composite Higgs (CH) models as a possible solution to the little hierarchy problem. After detailing the model building in a generic CH scenario, I will discuss our computation in a CH model based on the coset SU(3)xSU(3)/SU(3), demonstrating that it is possible to raise the CH cutoff scale to around 80TeV without tuning, at the expense of additional structure in the model. I will comment on some challenges associated with this model paradigm. Finally, I will discuss some phenomenological signatures of our model which are accessible at future colliders.
