Note on New KLT relations [PDF]

open access: yesJournal of High Energy Physics, 2010
In this short note, we present two results about KLT relations discussed in recent several papers. Our first result is the re-derivation of Mason-Skinner MHV amplitude by applying the S_{n-3} permutation symmetric KLT relations directly to MHV amplitude.

KLT factorization of winding string amplitudes [PDF]

open access: yesJournal of High Energy Physics, 2021
We uncover a Kawai-Lewellen-Tye (KLT)-type factorization of closed string amplitudes into open string amplitudes for closed string states carrying winding and momentum in toroidal compactifications.

KLT factorization of nonrelativistic string amplitudes

open access: yesJournal of High Energy Physics, 2022
We continue our study of the Kawai-Lewellen-Tye (KLT) factorization of winding string amplitudes in [1]. In a toroidal compactification, amplitudes for winding closed string states factorize into products of amplitudes for open strings ending on an array

Scattering Equations and KLT Orthogonality

open access: yes, 2013
Several recent developments point to the fact that rational maps from n-punctured spheres to the null cone of D dimensional momentum space provide a natural language for describing the scattering of massless particles in D dimensions.

Inverse of the String Theory KLT Kernel [PDF]

open access: yesJournal of High Energy Physics, 2017
The field theory Kawai-Lewellen-Tye (KLT) kernel, which relates scattering amplitudes of gravitons and gluons, turns out to be the inverse of a matrix whose components are bi-adjoint scalar partial amplitudes.

Projectively flat klt varieties [PDF]

open access: yesJournal de l’École polytechnique — Mathématiques, 2021
In the context of uniformisation problems, we study projective varieties with klt singularities whose cotangent sheaf admits a projectively flat structure over the smooth locus. Generalising work of Jahnke-Radloff, we show that torus quotients are the only klt varieties with semistable cotangent sheaf and extremal Chern classes. An analogous result for

Stringy KLT Relations on AdS

open access: yesJournal of High Energy Physics
We study the building blocks of open and closed string amplitudes on AdS. These are given by two infinite towers of world-sheet integrals generalising the Euler and complex beta functions respectively. We show that the open and closed building blocks are

The KLT Kernel in Twistor Space. [PDF]

open access: yesCommun Math Phys
Abstract The double copy relationship between Yang–Mills theory and general relativity can be stated in terms of a field theory Kawai–Lewellen–Tye (KLT) momentum kernel, which maps two colour-ordered gluon amplitudes to a graviton amplitude at tree-level.

Soft theorems and the KLT-relation [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract We find new relations for the non-universal part of the Yang-Mills amplitudes by combining the KLT-relation and the soft behavior of gauge and gravity amplitudes. We also extend the relations to include contributions from effective operators.
