Description
An extra dimension is one of the most attractive candidates beyond the Standard Model. In warped extra dimensional space-time, not only the gauge hierarchy problem but also quark-lepton mass hierarchy can be naturally explained. In this setup, a sizable parity violation through a Kaluza-Klein gluon exchange appears in the QCD process such as helicity dependent top pair production. We investigate this QCD parity violating process by use of the SO(5)×U(1) gauge-Higgs unification model. We evaluate LHC observable quantities, i.e., a charge asymmetry and a forward-backward asymmetry of the top pair production, and find that a sizable charge asymmetry can be observed with specific model parameters.
