Comment on "K^- d -> pi Sigma n reactions and structure of the Lambda(1405)" by S. Ohnishi, Y. Ikeda, T. Hyodo, E. Hiyama, W. Weise

TL;DR

This paper questions the originality of a previous work claiming to be the first full three-body calculation of the K^- d -> pi Sigma n reaction, highlighting concerns about priority and novelty.

Contribution

The authors challenge the claimed novelty of prior three-body calculations for the reaction, emphasizing the importance of accurate attribution in theoretical nuclear physics.

Findings

Questioned the priority of previous three-body calculations

Highlighted the need for proper attribution of scientific contributions

Emphasized the importance of accurate literature review

Abstract

We strongly doubt the claimed priority of this work as the first full three-body calculation of the considered reaction.
