Note Added to ``Baryon Asymmetry of the Universe in the Standard Model"

TL;DR

This paper critiques recent claims that higher order interactions reduce baryon asymmetry in the Standard Model, arguing that their computational approach is flawed and unreliable.

Contribution

It highlights the inconsistency and unitarity violations in previous methods, emphasizing the need for correct calculations in baryon asymmetry studies.

Findings

Previous claims are based on inconsistent calculations.

The methods used violate unitarity principles.

Conclusions of reduced baryon asymmetry are not justified.

Abstract

Recent papers by Gavela et al. and Huet et al. claim to have shown that incluion of higher order interactions between quasiparticles dramatically decreases the baryon asymmetry of the universe which can arise in the Minimal Standard Model. These papers employ an inconsistent calculational scheme which, for instance, violates unitarity. We argue that their method cannot be considered as reliable, and thus their conclusions cannot be considered as justified.
