Interpreting f0(600) and a0(980) as \bar q - q states from an Nf=3 Sigma Model with (Axial-)Vectors

TL;DR

This paper investigates whether the low-lying scalar mesons f0(600) and a0(980) can be interpreted as quark-antiquark states using a U(3)xU(3) Linear Sigma Model that includes vector and axial-vector mesons.

Contribution

It introduces a comprehensive U(3)xU(3) Linear Sigma Model with vector and axial-vector mesons to analyze the nature of scalar mesons f0(600) and a0(980).

Findings

Supports the interpretation of f0(600) and a0(980) as ar q - q states.

Provides a framework for analyzing scalar mesons within a chiral model.

Suggests compatibility of these mesons with quark-antiquark configurations.

Abstract

We address the question whether it is possible to interpret the low-lying scalar mesons f0(600) and a0(980) as \bar q - q states within a U(3)xU(3) Linear Sigma Model containing vector and axial-vector degrees of freedom.
