Higgs Decay into Two Photons in a Small and Warped Extra Dimension
Clara Hörner (MITP, PRISMA)

Randall-Sundrum (RS) models with a small and warped extra dimension offer solutions to the gauge and Yukawa hierarchy problems of the Standard Model of Particle Physics. In this context, loop induced scattering processes are of particular interest for the search after the validity of RS models, because RS models predict an infinite amount of heavy Kaluza-Klein particles that contribute as virtual particles in loops.
The talk will begin with a short introduction to RS models. In a second part, I will explain some steps of the calculation of the loop-induced Higgs decay into two photons in RS models together with a phenomenological analysis that compares the theoretical results of the RS models with the latest LHC results.
