Deriving motivic coactions and single-valued maps at genus zero from zeta generators

Hadleigh Frost, Martijn Hidding, Deepak Kamlesh +3

Multiple polylogarithms are equipped with rich algebraic structures including the motivic coaction and the single-valued map which both found fruitful applications in high-energy p…

Motivic coaction and single-valued map of polylogarithms from zeta generators

Hadleigh Frost, Martijn Hidding, Deepak Kamlesh +3

We introduce a new Lie-algebraic approach to explicitly construct the motivic coaction and single-valued map of multiple polylogarithms in any number of variables. In both cases, t…

Amplitudes at strong coupling as hyperkähler scalars

Hadleigh Frost, Ömer Gürdogan, Lionel Mason

Alday & Maldacena conjectured an equivalence between string amplitudes in AdS and null polygonal Wilson loops in planar super-Yang-Mills (SYM). At st…

The Algebraic Structure of the KLT Relations for Gauge and Gravity Tree Amplitudes

Hadleigh Frost

We study the Kawai-Lewellen-Tye (KLT) relations for quantum field theory by reformulating it as an isomorphism between two Lie algebras. We also show how explicit formulas for KLT…

A Lie bracket for the momentum kernel

Hadleigh Frost, Carlos R. Mafra, Lionel Mason

We develop new mathematical tools for the study of the double copy and colour-kinematics duality for tree-level scattering amplitudes using the properties of Lie polynomials. We sh…

Lie Polynomials and a Twistorial Correspondence for Amplitudes

Hadleigh Frost, Lionel Mason

We review Lie polynomials as a mathematical framework that underpins the structure of the so-called double copy relationship between gauge and gravity theories (and a network of ot…

Biadjoint scalar tree amplitudes and intersecting dual associahedra

Hadleigh Frost

We present a new formula for the biadjoint scalar tree amplitudes based on the combinatorics of dual associahedra. Our construction makes essential use of the cones in 'ki…
