Abstract
We present an all-loop dispersion integral, well-defined to arbitrary logarithmic accuracy, describing the multi-Regge limit of the 2->5 amplitude in planar N=4 super Yang-Mills theory. It follows from factorization, dual conformal symmetry and consistency with soft limits, and specifically holds in the region where th...

Introduction
From phenomenological studies to implications for quantum gravity, the description of scattering at high energies, or in the (multi-)Regge limit, is a subject with rich history and impact on many branches of theoretical physics. In the simplest case of 2\rightarrow 2 scattering, where the limit corresponds to a center-...

As such, it can be shown (for example by reflecting along the x-axis) that it rev...

Single-valued multiple polylogarithms
N-particle amplitudes in MRK are expected to be described by single-valued iterated integrals on the space of configurations of N-2 points on the Riemann sphere. This implies that they do not have branch cuts in the z_i plane, only isolated singularities when at least one of their symbol letters vanishes. These functio...

We stress that although the above formula, which is the 7-point analogue of (REF ), holds independently of how we choose to close the integration contours, it is only valid in the region z_1\ll 1,\,z_2\gg 1 which is convenient for expanding at weak coupling. This is because the \nu _1=\nu _2 residue is a simple integra...

(REF ). Then by virtue of (REF ) and (REF ), the same will be true for R_N^{(L)}, which thus completes the proof.A very similar statement also holds true beyond the MHV case, where it is more convenient to consider the entire superamplitude, rather than its gluonic component alone. This is then dual to a super-Wilson l...

Evaluation by Fourier-Mellin convolutions
Since Fourier-Mellin convolutions are also suited for the computation of hexagon NLLA amplitudes, convolutions in z_2 will behave in the desired fashion. Once again, we have to ensure that convolutions in z_1 do not spoil our results, which means that convolutions with \begin{}E\end{}(z_1) and \begin{}H\end{}^{(1)}(z_1...

Conclusions
In this paper, we took a decisive step towards the description of \begin{}N\end{}=4 super-Yang Mills amplitudes with more than six legs in the multi-Regge limit, to arbitrary logarithmic accuracy. Focusing on the 2\rightarrow 5 amplitude, we first succeeded in describing it in this limit in terms of the all-loop disper...

Conclusions
Using the method described in REF , we have already extracted the NNLO correction to the central emission vertex, up to transcendental constants, from the 3-loop heptagon symbol , and although beyond the scope of this paper, it is a straightforward extension to do the same at N^3LO, from the corresponding 4-loop symbol...

Although the representation obtained depends on the choice of the contour \gamma , the actual function obtained only depends on the choice of base point (in this case the origin in (\rho _1,\hat{\rho }_2) coordinates.
