Phenomenology of Universal Extra Dimensions with Bulk-Masses and Brane-Localized Terms

Understand

We present a general model with universal extra dimensions in the presence of the bulk fermion masses and boundary localized kinetic terms, which are generically allowed by symmetries of five dimensional gauge theory.

• We provide a comprehensive analysis for a general UED model, including Kaluza-Klein mass spectra, their interactions with the SM particles, and constraints from LHC, electroweak tests, and dark matter experiments.
• Finally we show current bounds on the size of allowed universal bulk mass and universal brane-localized terms.
