Deeply Virtual Compton Scattering and Higgs Production Using the Pomeron in AdS

In the past decade overwhelming evidence has emerged for a conjectured duality between a wide class of gauge theories in d dimensions and string theories on asymptotically AdSd+1 spaces. We apply this duality to scattering processes that occur via Pomeron exchange. First we develop the Pomeron in string theory, as done by Brower, Polchinski, Strassler and Tan,1 showing that it naturally emerges as the Regge Trajectory of the AdS graviton. Next we apply the AdS Pomeron to the study of Deeply Virtual Compton Scattering (DVCS), and see that our model gives good results when compared to HERA data.2 We then show how we can extend our results to double Pomeron exchange, and apply it to developing a formalism for the study of double diffractive Higgs production.3 Pomeron-Graviton Duality: In the Regge limit, s t, it can be shown for a wide range of scattering processes that the amplitude is dominated by Pomeron exchange. Traditionally this has been modeled at weak coupling using perturbative QCD, but we will use here a formula-tion based on gauge/gravity duality, or the AdS/CFT correspondence, of which one particular example is the duality between N = 4 SYM and Type IIB string theory on AdS5 × S5. This approach has the advantages of allowing us to study the strong coupling region, providing
