Feynman diagrams and the large charge expansion in 3 − ε dimensions [PDF]
Physics Letters B, 2019 In arXiv:1909.01269 it was shown that the scaling dimension of the lightest charge n operator in the U ( 1 ) model at the Wilson-Fisher fixed point in D = 4 − e can be computed semiclassically for arbitrary values of λn, where λ is the perturbatively ...

Structure of light-front vacuum sector diagrams
Physics Letters B, 2019 We study the structure of scalar field light-front quantization vacuum graphs. In instant-time quantization both non-vacuum and vacuum graphs can equivalently be described by either the off-shell four-dimensional Feynman diagram approach or the on-shell ...

Note on the Labelled tree graphs
Journal of High Energy Physics, 2020 In the CHY-frame for the tree-level amplitudes, the bi-adjoint scalar theory has played a fundamental role because it gives the on-shell Feynman diagrams for all other theories.

A Feynman diagram analyzer DIANA [PDF]
Computer Physics Communications, 2000 A C-program DIANA (DIagram ANAlyser) for the automatic Feynman diagram evaluation is presented. It consists of two parts: the analyzer of diagrams and the interpreter of a special text manipulating language. This language is used to create a source code for analytical or numerical evaluations and to keep the control of the process in general.

Opportunities and Challenges of Using Feynman Diagrams with Upper Secondary Students
Physics, 2022 Particle physics is an exciting subject for high school students, and there have been various approaches on how to introduce the topic in the classroom. Feynman diagrams (FDs) are an often-used form of representation in particle physics and could play an

Determinant Monte Carlo for irreducible Feynman diagrams in the strongly correlated regime [PDF]
Physical review B, 2017 We introduce a numerically exact method for efficient summation of irreducible Feynman diagrams for the fermionic self-energy in the thermodynamic limit. The technique, based on the Diagrammatic Determinant Monte Carlo, allows us to reach unprecedentedly

Hurwitz numbers from Feynman diagrams [PDF]
Theoretical and mathematical physics, 2020 To obtain a generating function of the most general form for Hurwitz numbers with an arbitrary base surface and arbitrary ramification profiles, we consider a matrix model constructed according to a graph on an oriented connected surface \documentclass ...

The chirality-flow formalism for the standard model
European Physical Journal C: Particles and Fields, 2021 In a recent paper we introduced the chirality-flow formalism, a method for simple and transparent calculations of Feynman diagrams based on the left- and right-chiral $$\mathfrak {sl}(2,\mathbb {C})$$ sl ( 2 , C ) nature of spacetime.
