The real problem with perturbative quantum field theory

JD Fraser - The British Journal for the Philosophy of Science, 2020 - journals.uchicago.edu
The perturbative approach to quantum field theory (QFT) has long been viewed with
suspicion by philosophers of science. This article offers a diagnosis of its conceptual …

On the interpretation of Feynman diagrams, or, did the LHC experiments observe Hγγ?

O Passon - European Journal for Philosophy of Science, 2019 - Springer
According to the received view Feynman diagrams are a bookkee** device in complex
perturbative calculations. Thus, they do not provide a representation or model of the …

The development of computational methods for Feynman diagrams

RV Harlander, JP Martinez - The European Physical Journal H, 2024 - Springer
Over the last 70 years, Feynman diagrams have played an essential role in the development
of many theoretical predictions derived from the standard model Lagrangian. In fact, today …

The magic of Feynman's QED: from field-less electrodynamics to the Feynman diagrams

O Darrigol - The European Physical Journal H, 2019 - Springer
For some time, even after the Feynman diagrams and rules were publicly known, the
foundations of Feynman's quantum electrodynamics remained mostly private. Its stupendous …

What is Quantum Field Theory? Idealisation, Explanation and Realism in High Energy Physics.

JD Fraser - 2016 - etheses.whiterose.ac.uk
Quantum field theory (QFT) poses a challenge to the orthodox methodological framework of
the philosophy of science. The first step of investigating a physical theory, it is commonly …

How to study virtual entities historically? A proposal

M Ehberger - Perspectives on Science, 2024 - direct.mit.edu
This paper will not present a case study of the historical development of a virtual entity.
Rather, I will develop an outlook on virtual entities in the sciences and propose a …

The exigencies of war and the stink of a theoretical problem: Understanding the genesis of Feynman's quantum electrodynamics as mechanistic modelling at different …

A Wüthrich - Perspectives on Science, 2018 - direct.mit.edu
Much of Feynman's method relied on a diagrammatic representation of the physical
processes as well as, at the same time, of the mathematical expressions used to describe …

Solutions in constructive field theory

L Hancox-Li - Philosophy of Science, 2017 - cambridge.org
Constructive field theory aims to rigorously construct concrete, nontrivial solutions to
Lagrangians used in particle physics. I examine the relationship of solutions in constructive …

The Use of Feynman Diagrams in Physics Education: Opportunities, Challenges, Practices

MN Dahlkemper - 2024 - ediss.uni-goettingen.de
This thesis explores the potential of Feynman diagrams as educational tools in upper
secondary physics education, specifically for teaching particle physics concepts. It is set …

Against the impossible picture: Feynman's heuristics in his search for a divergence-free quantum electrodynamics

A Wüthrich - 2011 - philsci-archive.pitt.edu
Arguably, the development of Feynman diagrams not only resulted in a useful tool for
calculations but also brought about deep conceptual changes in the theory of quantum …
