Four-Fermion Interaction Approximation of the Intermediate Vector Boson Model

Year: 2024

Type: article

Abstract: In the present paper, we show that when the mass of the Proca field is large enough, the Dirac-Proca equations are approximated by the cubic Dirac equation. This justifies the four-fermion interaction approximation of the intermediate vector boson model in a mathematically rigorous sense. The proof is based on the Strichartz estimate of the Proca sector with mass parameter.
