Feynman diagrams and $Ω$-deformed M-theory [PDF]

open access: diamondSciPost Physics, 2021
We derive the simplest commutation relations of operator algebras associated to M2 branes and an M5 brane in the $\Omega$-deformed M-theory, which is a natural set-up for Twisted holography.

Group invariants for Feynman diagrams [PDF]

open access: diamondSciPost Physics Proceedings, 2023
It is well-known that the symmetry group of a Feynman diagram can give important information on possible strategies for its evaluation, and the mathematical objects that will be involved. Motivated by ongoing work on multi-loop multi-photon amplitudes in

Combinatorial summation of Feynman diagrams. [PDF]

open access: yesNat Commun, 2023
Feynman’s diagrammatic series is a common language for a formally exact theoretical description of systems of infinitely-many interacting quantum particles, as well as a foundation for precision computational techniques.

Feynman rules for scalar conformal blocks [PDF]

open access: yesJournal of High Energy Physics, 2022
We complete the proof of “Feynman rules” for constructing M-point conformal blocks with external and internal scalars in any topology for arbitrary M in any spacetime dimension by combining the rules for the blocks (based on their Witten diagram ...

First look at the evaluation of three-loop non-planar Feynman diagrams for Higgs plus jet production [PDF]

open access: diamondJournal of High Energy Physics, 2023
We present new computations for Feynman integrals relevant to Higgs plus jet production at three loops, including first results for a non-planar class of integrals.

Gravitational lensing of the CMB: A Feynman diagram approach

open access: diamondPhysics Letters B, 2014
We develop a Feynman diagram approach to calculating correlations of the Cosmic Microwave Background (CMB) in the presence of distortions. As one application, we focus on CMB distortions due to gravitational lensing by Large Scale Structure (LSS).

Integrable Feynman graphs and Yangian symmetry on the loom

open access: yesJournal of High Energy Physics, 2023
We present significant evidence that the powerful property of Yangian invariance extends to a new large class of conformally invariant Feynman integrals. Our results apply to planar Feynman diagrams in any spacetime dimension dual to an arbitrary network

Understanding zeros and splittings of ordered tree amplitudes via Feynman diagrams [PDF]

open access: greenJournal of High Energy Physics
In this paper, we propose new understandings for recently discovered hidden zeros and novel splittings of scattering amplitudes, by utilizing Feynman diagrams.

A procedure g5anchor to anchor γ 5 in Feynman diagrams for the Standard Model

open access: yesJournal of High Energy Physics
We present a procedure g5anchor to anchor γ 5 in the definition of a Dirac trace with γ 5 in Dimensional Regularization (DR) in Feynman diagrams for the Standard Model, based on a recent revision of the works by Kreimer, Gottlieb and Donohue.
