The Neutral $Z$ boson pair production due to radion resonance at the LargeHadron Collider (LHC) is an interesting process to explore the notion of warpedgeometry (Randall-Sundrum model). Because of the enhanced coupling of radionwith a pair of gluons due to trace enomaly and top(quark) loop, the radion canprovide larger event rate possibility as compared to any New Physics effect.Using the proper radion-top-antitop (with the quarks being off-shell) coupling,we obtain the correct radion production rate at LHC and explore severalfeatures of a heavier radion decaying into a pair of real $Z$ bosons whichsubsequently decays into charged $4 l (l=e, \mu)$ leptons (the gold-platedmode). Using the signal and background event rate, we obtain bounds on radionmass $m_\phi$ and radion vev $\vphi$ at the $5\sigma$, $10\sigma$ discoverylevel.Comment: 17 pages, 4 figures, minor changes in the text, result unchanged.
