Here we propose a simple self-consistent holographic framework capable of providing phenomenologically compelling estimates of diffractive cross sections at the LHC. As in the traditional weak coupling approach, we anticipate that several phenomenological parameters must be tested and calibrated through factorization for a self-consistent description of other diffractive process such as total cross sections, deep inelastic scattering and heavy quark production in the central region.

In leading order of the leading 1/Nc expansion this exchange process has been identified as the BFKL Pomeron or its strong AdS dual the closed string graviton [1]. However difference of particle antiparticle cross sections are given by a so-called Odderon carrying C = -1 quantum numbers identified in weak coupling with odd numbers of exchanged gluons. Here we show that the dual description associates this with the Neveu-Schwartz (Bµν ) sector of closed string theory. We also discuss the extension of the strong coupling treatment to central diffractive Higgs production at LHC. * speaker EDS'09

However the difference of particle anti-particle cross sections are given by a so-called Odderon, carrying C = -1 vacuum quantum numbers identified in weak coupling with odd numbers of exchanged gluons. Here we show that in the dual description the Odderon is the Reggeized Kalb-Ramond field (B�ν ) in the Neveu-Schwartz sector of closed string theory. To first order in strong coupling, the high energy contribution of Odderon is evaluated for N = 4 Super Yang-Mills by a generalization of the gravity dual analysis for Pomeron in Ref. (1). The con- sequence of confinement on the Odderon are estimated in the confining QCD-like AdS5 hardwall model of Polchinski and Strassler (2).

We discuss how, using String/Gauge duality, these can be identified with a reggeized Graviton and the anti-symmetric Kalb-Ramond fields in AdS background. With confinement, these Regge singularities interpolate with glueball states. We also discuss unitarization based on eikonal sum in AdS.

Subsequently Brower, Polchinski, Strassler and Tan (BPST) computed the strong coupling kernel for the vacuum (or Pomeron) contribution to total cross sections. By identifying deep inelastic scattering with virtual photon total cross section, this allows a self consistent description at small-x where the dominant contribution is the vacuum exchange process. Here we formulate this contribution and compare it with HERA small-x DIS scattering data. We find that the BPST kernel along with a very simple local approximation to the proton and current “wave functions” gives a remarkably good fit not only at large Q 2 dominated by conformal symmetry but also extends to small Q 2, supplemented by a hard-wall cut-off of the AdS in the IR. We suggest that this is a useful phenomenological parametrization with implications for other diffractive processes, such as double diffractive Higgs production.

We emphasize the importance of confinement, which in this context corresponds to a deformation of AdS5 geometry in the IR. The holographic Pomeron provides a very good fit 4 to the combined data from HERA for Deep Inelastic Scattering at small x, lending new confidence to this AdS dual approach to high energy diffractive scattering.
