“…It has also been suggested recently, for N = 4 SYM, that the latter remains exactly at j = 1, to all orders in weak coupling [54,55]. Interestingly, these correspond nicely with strong coupling analysis in the diffusion limit [20,56]. 12 Actually, since [19] also computes b 4,0 = 31/128 and b 4,1 = 901 − 5520ζ(3) − 5120ζ(5) − 3640ζ(7) /1024, we can determine c 7,3 = 391/1024 and c 8,4 = 15081 − 27120ζ(3) − 12320ζ(5) − 3640ζ(7) /8192.…”

From the perspective of AdS/CFT the Pomeron is identified with a Reggeized Graviton, while the Odderons correspond to Reggeized anti-symmetric AdS 5 Kalb-Ramond tensorfields. In this paper, we consider the strong coupling expansion of the dimension of the leading twist operators dual to these Regge trajectories, ∆(j), to determine its analytic continuation in j beyond the diffusion limit. In particular, we compute the strong coupling expansion of the intercept to order λ −3 , where λ is the t'Hooft coupling, for both the Pomeron, which is C = +1 crossing-even, and the "Odderons", which are the leading C = −1 crossing-odd Regge singularities. We discuss the spectral curves of the class of single-trace operators to which these string modes couple.

“…In order to explain this, the Odderon has to have a small imaginary part (and the Pomeron has a small real part). It may be possible to generalize our model to accommodate this effect, for example, by using the dispersion relation or invoking Regge theory or the AdS/CFT correspondence [54]. This is however beyond the scope of this work.…”

We introduce a new model of near-forward elastic proton–(anti)proton scattering at high energy based on the modern formulation of Pomeron and Odderon in terms of Wilson lines and generalized transverse momentum dependent distributions. We compute the helicity-dependent elastic amplitudes $$\phi _{1,2,3,4,5}$$ϕ1,2,3,4,5 in this model and study their energy dependence from the nonlinear small-x evolution equations. While both Pomeron and Odderon contribute to helicity-flip processes in general, in the forward limit $$t=0$$t=0 only the double helicity-flip amplitude $$\phi _2$$ϕ2, dominated by the spin-dependent Odderon, survives. This may affect the extraction of the $$\rho $$ρ parameter as well as the total cross section in the LHC energy domain and beyond.

“…The odderon has been identified with the fluctuations of the anti-symmetric Neveu-SchwarzNeveu-Schwarz (NS-NS) 2-form B M N in the bulk [36,37]. In the dual holographic description used here, the contribution to the effective action of the string that is odd under the d → − d operation should arise from the coupling of the NS 2-form field to the string in the NambuGoto action…”

Azimuthal asymmetries in high-energy collisions of protons with holographic shockwaves

Large azimuthal quadrupole and octupole asymmetries have recently been found in p+Pb collisions at the LHC. We argue that these might arise from a projectile dipole scattering off fluctuations in the target with a size on the order of the dipole. In a holographic scenario, parity even angular moments v 2n are generated by the real part of the light-like Wilson loop due to the contribution from the background metric to the Nambu-Goto action. On the other hand, parity odd moments v 2n+1 must arise from the imaginary part of the light-like Wilson loop, which is naturally induced by a fluctuating Neveu-Schwarz 2-form. *
