Description

We discuss conformal Pomeron and Odderon using AdS/CFT, or, equivalently, Pomeron and Odderon in N = 4 SYM, in strong coupling. We explore the relation between the 'Basso-expansion' and the Delta-j curve at strong coupling, and we demonstrate how it can be applied to other Regge intercepts in addition to Pomeron. In particular, we focus on 'Odderons' which are the leading crossing-odd, C = -1, Regge singularities. From the perspective of AdS/CFT, while Pomeron can be identified with a Reggeized Graviton, Odderons correspond to Reggeized anti-symmetric AdS5 Kalb-Ramond tensor-fields. We identify the class of single-trace operators to which the string modes couple to and discuss their anomalous dimension curves. This information is the applied to calculate the Odderon intercept beyond leading order.
