LHC Phenomenology of Lowest Massive Regge Recurrences in the Randall-Sundrum Orbifold
arXiv:1006.3044 · doi:10.1103/PhysRevD.82.106010
Abstract
We consider string realizations of the Randall-Sundrum effective theory for electroweak symmetry breaking and explore the search for the lowest massive Regge excitation of the gluon and of the extra (color singlet) gauge boson inherent of D-brane constructions. In these curved backgrounds, the higher-spin Regge recurrences of Standard Model fields localized near the IR brane are warped down to close to the TeV range and hence can be produced at collider experiments. Assuming that the theory is weakly coupled, we make use of four gauge boson amplitudes evaluated near the first Regge pole to determine the discovery potential of LHC. We study the inclusive dijet mass spectrum in the central rapidity region |y_{jet}| < 1.0 for dijet masses M \geq 2.5 TeV. We find that with an integrated luminosity of 100 fb^{-1}, the 5σdiscovery reach can be as high as 4.7 TeV. Observations of resonant structures in pp \rightarrow direct γ+ jet can provide interesting corroboration for string physics up to 3.0 TeV. We also study the ratio of dijet mass spectra at small and large scattering angles. We show that with the first fb^{-1} such a ratio can probe lowest-lying Regge states for masses \sim 2.5 TeV.
