Reply to the Comment by Harada, Sannino and Schechter on "Confirmation of the Sigma Meson"

TL;DR

This paper defends the existence of the broad sigma meson near 500 MeV, addressing critiques about the necessity of a detailed crossing symmetric form for data interpretation.

Contribution

It provides a rebuttal to previous comments, reinforcing the evidence for the sigma meson and clarifying the theoretical approach needed for data analysis.

Findings

Supports the existence of the broad sigma meson near 500 MeV

Addresses the importance of crossing symmetry in data analysis

Clarifies the theoretical assumptions in sigma meson studies

Abstract

We reply to the comment of Harada, Sannino and Schechter (hep-ph/9609428) on our recent paper in the Phys. Rev. Letters on the sigma meson. This concerns the question, raised by Isgur and Speth in another comment, of whether a detailed crossing symmetric form is necessary to understand the data. The discussion gives further support on the existence of the broad sigma near 500 MeV.
