Composite Higgs models and the AdS/CFT Correspondence — Johanna Erdmenger, Werner Porod, and •Deepali Singh — Julius-Maximilians-Universität Würzburg, Germany

Symmetry groups and their representations play a crucial role in understanding fundamental physics, from particle phenomenology to holographic duality. Symmetries have also given us an insight into solving issues like the hierarchy problem. One such example is the framework of Composite Higgs models which addresses the hierarchy problem by interpreting the Higgs boson as a pseudo-Nambu-Goldstone boson arising from a global symmetry breaking. We will discuss how AdS/CFT offers powerful tools to study Composite Higgs scenarios by leveraging the duality between strongly coupled gauge theories and weakly coupled gravitational theories in one higher dimension. In particular, we will consider models in which the global group SU(4)xSU(4) gets broken to the diagonal SU(4). We will use gauge/gravity duality to calculate the spectrum of bosonic bound states emerging in Composite Higgs models.
