The quintic interaction vertex in light-cone gravity
TLDR
In this article, the complete quintic interaction vertex was derived for pure gravity in light-cone gauge and derived the complete KLT vertex up to quartic order, where the Kawai-Lewellen-Tye relations can be made manifest at the level of the Einstein-Hilbert Lagrangian.About:

The kinematic algebra from the self-dual sector
Ricardo Monteiro,Donal O'Connell +1 more
TL;DR: In this article, a diffeomorphism Lie algebra in the self-dual sector of Yang-Mills theory is identified, and it determines the kinematic numerators of tree-level MHV amplitudes in the full theory.

Colour-Kinematics duality for one-loop rational amplitudes
TL;DR: In this article, the duality of colour-kinematics duality at one loop using the self-dual sector as a starting point was shown to exist in pure Yang-Mills theory for two infinite classes of amplitudes: amplitudes with any number of particles either all of the same helicity or with one particle helicity opposite the rest.

Investigations into Light-front Quartic Interactions for Massless Fields (I): Non-constructibility of Higher Spin Quartic Amplitudes
TL;DR: In this article, the existence of quartic contact interactions unrelated to cubic interactions by Poincare symmetry indicates that the higher spin S-matrix is not constructible, and the quartic amplitude based no-go results derived by BCFW recursion for Minkowski higher spin massless fields may be circumvented.

Gravitino interactions from Yang-Mills theory
TL;DR: In this paper, the Kawai-Lewellen-Tye factorization for gravitinos at an off-shell Lagrangian level was investigated. But the results were not explicitly verified until five-point scattering.

Investigations into light-front interactions for massless fields (I): non-constructibility of higher spin quartic amplitudes
TL;DR: In this article, the existence of quartic contact interactions unrelated to cubic interactions by Poincare symmetry indicates that the higher spin S-matrix is not constructible, and therefore quartic amplitude based no-go results derived by BCFW recursion for Minkowski higher spin massless fields may be circumvented.

A Relation Between Tree Amplitudes of Closed and Open Strings
TL;DR: In this article, the authors derive a formula which expresses any closed string tree amplitude in terms of a sum of the products of appropriate open string tree amplitudes, which is applicable to the heterotic string as well as to the closed bosonic string and type II superstrings.

Fusing gauge theory tree amplitudes into loop amplitudes
TL;DR: In this paper, a large class of one-loop amplitudes for massless particles that can be constructed via unitarity from tree amplitudes, without any ambiguities, is identified.

MHV vertices and tree amplitudes in gauge theory
TL;DR: In this paper, a tree amplitudes in Yang-Mills theory can be constructed from tree graphs in which the vertices are tree level MHV scattering amplitudes, continued off shell in a particular fashion.

Light-cone superspace and the ultraviolet finiteness of the N=4 model
TL;DR: In this paper, it was shown that the N = 4 model is completely free of ultraviolet divergences in any order of perturbation theory, and that the β-function vanishes in any θ-function in any light-cone frame.

The Six Gluon Process as an Example of Weyl-Van Der Waerden Spinor Calculus
Frits A. Berends,W.T. Giele +1 more
TL;DR: In this paper, the use of Weyl-van der Waerden spinors and its related calculus with dotted and undotted indices is advocated for those high energy processes where masses can be neglected.
