The Two-Loop Hexagon Wilson Loop in N = 4 SYM | Vittorio Del Duca

8 Mar 2010 | Abstract: | In the planar N=4 supersymmetric Yang-Mills theory, the conformal symmetry
constrains multi-loop n-edged Wilson loops to be given in terms of the one-loop
n-edged Wilson loop, augmented, for n greater than 6, by a function of
conformally invariant cross ratios. That function is termed the remainder
function. In a recent paper, we have displayed the first analytic computation
of the two-loop six-edged Wilson loop, and thus of the corresponding remainder
function. Although the calculation was performed in the quasi-multi-Regge
kinematics of a pair along the ladder, the Regge exactness of the six-edged
Wilson loop in those kinematics entails that the result is the same as in
general kinematics. We show in detail how the most difficult of the integrals
is computed, which contribute to the six-edged Wilson loop. Finally, the
remainder function is given as a function of uniform transcendental weight four
in terms of Goncharov polylogarithms. We consider also some asymptotic values
of the remainder function, and the value when all the cross ratios are equal. | Source: | arXiv, 1003.1702 | Services: | Forum | Review | PDF | Favorites |
