Phenomenology of spinless adjoints in two Universal Extra Dimensions

Understand

We discuss the phenomenology of $(1,1)$-mode adjoint scalars in the framework of two Universal Extra Dimensions.

• The Kaluza-Klein (KK) towers of these adjoint scalars arise in the 4-dimensional effective theory from the 6th component of the gauge fields after compactification.
• Adjoint scalars can have KK-number conserving as well as KK-number violating interactions.
• We calculate the KK-number violating operators involving these scalars and two Standard Model fields.
