TL;DR

This paper responds to criticisms of previous calculations of quarkonium and glueball scalars, clarifying their relation to full QCD and defending the validity of their approach.

Contribution

It provides a detailed clarification of the authors' methods and addresses misconceptions about their calculations in the context of full QCD.

Findings

Clarifies the relation of their calculations to full QCD

Addresses and refutes criticisms by Lee and Weingarten

Supports the validity of their original approach

Abstract

Lee and Weingarten have recently criticized our calculation of quarkonium and glueball scalars as being "incomplete" and "incorrect". Here we explain the relation of our calculations to full QCD.
