Comment on "Applications of Two-Body Dirac Equations to the Meson Spectrum with Three versus Two Covariant Interactions, SU(3) Mixing, and Comparison to a Quasipotential Approach'' by H. W. Crater and J. Schiermeyer

TL;DR

This paper responds to criticisms of the quasipotential approach used in a relativistic quark model for meson spectra, discussing its validity and implications in light of prior work on two-body Dirac equations.

Contribution

The authors provide a detailed rebuttal to critiques of their quasipotential method, clarifying its application and robustness in modeling meson spectra.

Findings

Reaffirmation of the quasipotential approach's validity

Clarification of differences with two-body Dirac equations

Discussion on implications for meson spectrum modeling

Abstract

We present some considerations in connection with the paper arXiv:1004.2980 [hep-ph] and give a response to the criticism of the quasipotential approach in our relativistic quark model.
