Challenges with Internal Photons in Constructive QED
Neil Christensen, Harold Diaz-Quiroz, Bryan Field +2
We find the correct spinor amplitude for a simple photon-mediated process and show that, in contrast, the result for the same process using the standard constructive techniques do…
2-, 3- and 4-Body Decays in the Constructive Standard Model
Neil Christensen, Bryan Field, Annie Moore +1
We further develop the massive constructive theory of the Standard Model and use it to calculate the amplitude and squared amplitude for all two-body decays, a collection of weak t…
The Constructive Standard Model: Part I
Neil Christensen, Bryan Field
In this paper, we construct the complete set of minimal 3-point vertices for the massive Standard Model (SM) based purely on symmetry principles, mass dimension and high-energy beh…
A First Step Towards Effectively Nonperturbative Scattering Amplitudes in the Perturbative Regime
Neil Christensen, Joshua Henderson, Santiago Pinto +1
We propose an effectively nonperturbative approach to calculating scattering amplitudes in the perturbative regime. We do this in a discretized momentum space by using the QSE meth…
Diagonalizing the Hamiltonian of Theory in 2 Space-Time Dimensions
Neil Christensen
We propose a new non-perturbative technique for calculating the field-theory S-matrix directly from the eigenstates of the Hamiltonian. Our method involves a discretized momentum s…
Validity of One-Dimensional QED for a System with Spatial Symmetry
Q. Z. Lv, N. D. Christensen, Q. Su +1
We examine the accuracy of an intrinsically one-dimensional quantum electrodynamics to predict accurately the forces and charges of a three-dimensional system that has a high degre…
