A compact analytic formula is presented for the two-loop six-particle maximally helicity violating remainder function in N=4 supersymmetric Yang-Mills theory in terms of the classical polylogarithm functions Lik with cross ratios of momentum twistor invariants as their arguments.

We construct light-cone gauge superstring field theory in a pp-wave background with Ramond-Ramond flux. The leading term in the interaction Hamiltonian is determined up to an overall function of…

An AdS2 black hole spacetime is an AdS2 spacetime together with a preferred choice of time. The Boulware, Hartle-Hawking and SL(2,) invariant vacua are constructed, together with their Green…

Abstract: We find the moduli space of multi-solitons in noncommutative scalar field theories at large θ, in arbitrary dimension. The existence of a non-trivial moduli space at leading order in 1/θ is…

A bstractIn this paper we study motivic amplitudes — objects which contain all of the essential mathematical content of scattering amplitudes in planar SYM theory in a completely canonical way, free…
Dressing the Giant Magnon

We apply the dressing method to construct new classical string solutions describing various scattering and bound states of magnons. These solutions carry one, two or three SO(6) charges and…
From twistor string theory to recursion relations
- M. Spradlin, A. Volovich
- Mathematics
- 1 September 2009
Witten's twistor string theory gives rise to an enigmatic formula [1] known as the ``connected prescription'' for tree-level Yang-Mills scattering amplitudes. We derive a link representation for the…
Superstring interactions in a pp-wave background II
- M. Spradlin, A. Volovich
- Physics
- 10 June 2002
In type-IIB light-cone superstring field theory, the cubic interaction has two pieces: a delta-functional overlap and an operator inserted at the interaction point. In this paper we extend our…
On light cone SFT contact terms in a plane wave
