Higgs production and decay processes via loop diagrams in various 6D Universal Extra Dimension Models at LHC

Understand

We calculate loop-induced Higgs production and decay processes which are relevant for the LHC in various six-dimensional Universal Extra Dimension models.

• More concretely, we focus on Higgs production through gluon fusion and Higgs decay into two photons induced by loop diagrams.
• They are one-loop leading processes and the contribution of Kaluza-Klein particles is considered to be significant.
• These processes are divergent in six dimensions.
