Higgs Production via gg→ h in a Warped Extra Dimension: Part I — •Raoul Malm, Kristiane Novotny, Christoph Schmell, and Matthias Neubert — Institut für Physik, JGU Mainz

Precise measurements of the Higgs-like boson production and decay properties allow to test the Standard Model description of electroweak symmetry breaking and to search for indirect hints of new physics. Being loop-suppressed the Higgs production cross section via gluon-gluon fusion can be significantly affected by new heavy particles running inside the triangle.

This talk will discuss the calculation of the leading-order contribution from a 5D perspective within the Minimal Randall-Sundrum Model, that belongs to the class of warped extra-dimensional theories with a TeV-brane localized Higgs boson, being capable of addressing the gauge and Yukawa hierarchy problems. Special focus will be placed on the regularization prescription of the Higgs profile and its relation to the cutoff leading to the distinction between a brane and a narrow-bulk Higgs scenario.
