Comment on paper arXiv:0902.3613 by P. Bicudo et al

TL;DR

This paper critically examines the quartet basis and high-momentum truncation scheme proposed for Delta resonances, questioning the validity and justification of the original claims by Bicudo et al.

Contribution

It provides a detailed critique of the methodology and claims made in the original paper, highlighting areas lacking proper justification.

Findings

Not all results and claims are properly justified

Questions the validity of the quartet basis for Delta resonances

Challenges the high-momentum truncation scheme proposed

Abstract

In the Comment we scrutinized the quartet basis for the Delta resonances, and the high-momentum truncation scheme, suggested by Bicudo et al. Not all the results and claims has been properly justified by the authors.
