The AdS/CFT graviton unifies Regge and hard gluon mechanism for N=4 super Yang-Mills with implication for hadronic diffractive cross sections at high (LHC and beyond) energies. The Graviton/Pomeron dominance in the 'tHooft's shock wave analysis will be explain for highly peripheral scattering. The impact parameters and virtuality are combined into an AdS3 subspace of AdS5, providing a new tool to understand the saturation of the Froissart bound and a unified framework for diffractive production.

This talk is a survey of two on-going studies involving dynamical lattice fermions in the adjoint representation of SU(2), exploiting the considerable computing infrastructure at Rensselaer. (1) Gluino condensation and other results using RPI's BlueGene/L cluster, part of the CCNI supercomputing complex (world's 7th most powerful). This Domain Wall Fermion computation will give, for the first time, continuum extrapolations of important quantities such as the condensate and string tension. (2) Two flavors of adjoint Wilson fermions, a candidate for walking technicolor models due to a very small perturbative beta function. We are testing this idea with an extensive study of the lattice phase diagram.
