Learning Scattering Amplitudes with Transformer Reinforcement Learning
Philip Velie, Tianji Cai, Piyush Jha +2
We introduce a transformer reinforcement learning algorithm that learns to solve high loop-level scattering amplitudes in planar N = 4 Super Yang-Mills theory. Our algorithm improv…
Constructing Concrete Colour Tensors for Simple Lie Algebras
Jacob L. Bourjaily, Michael Plesser, Philip Velie
We describe the implementation and use of colour_tensors: a Mathematica package built for the concrete construction of explicit colour tensors involving arbitrarily charged particl…
Tree Amplitudes with Charged Matter in Pure Gauge Theory
Jacob L. Bourjaily, Michael Plesser, Philip Velie
We describe the implementation and usage of `fermionic_amplitudes.m', a Mathematica package for the computation of tree amplitudes involving arbitrary numbers of gauge bosons and a…
A bijection for tuples of commuting permutations and a log-concavity conjecture
Abdelmalek Abdesselam, Pedro Brunialti, Tristan Doan +1
Let denote the number of -tuples of commuting permutations of elements whose permutation action results in exactly orbits or connected components. We pr…
Parametrization of Quark and Gluon Generalized Parton Distributions in a Dynamical Framework
Brandon Kriesten, Philip Velie, Emma Yeats +2
We present a parametrization of the chiral even generalized parton distributions, , , , , for the quark, antiquark and gluon, in the perturbativ…
