Query: QCD parity violation at LHC in warped extra dimension   Extra dimension is one of the most attractive candidates beyond the Standard
Model. In warped extra dimensional space-time, not only gauge hierarchy problem
but also quark-lepton mass hierarchy can be naturally explained. In this setup,
a sizable parity violation through Kaluza-Klein gluon exchange appears in QCD
process such as helicity dependent top pair production. We investigate this QCD
parity violating process by use of $SO(5) \times U(1)$ 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.
