SPINAS: Spinor Amplitude Subroutines for Constructive Diagram Evaluations
Neil Christensen
SPINAS is a C++ package created for the implementation and numerical computation of phase-space points of constructive amplitudes in particle physics. This package contains a suite…

A Complete Set of 4-Point Amplitudes in the Constructive Standard Model
Neil Christensen
We present a complete set of 4-point amplitudes in the constructive Standard Model at tree level. Any 4-point amplitude can be obtained from the results presented here by a suitabl…

Perturbative Unitarity and the 4-Point Vertices in the Constructive Standard Model
Neil Christensen
We find a complete set of 4-point vertices in the Constructive Standard Model (CSM). This set is smaller than in Feynman diagrams as the CSM does not need or allow any additional 4…
