f_{2}(1270),$ $a_{1}(1260)$ and $f_{0}(1370)$ as dynamically reconstructed quark-antiquark states

TL;DR

This paper justifies interpreting the resonances f_{2}(1270), a_{1}(1260), and f_{0}(1370) as quark-antiquark states, showing compatibility between quark model and Bethe-Salpeter approaches.

Contribution

It demonstrates that the quark model and Bethe-Salpeter studies are compatible approaches to describing these resonances as quark-antiquark states.

Findings

Quark model and Bethe-Salpeter results are compatible.

Resonances can be understood as quark-antiquark states.

The interpretation is theoretically justified.

Abstract

It is explained why the interpretation of the resonances $f_{2}(1270),$ $a_{1}(1260)$ and $f_{0}(1370)$ as quark-antiquark states is legitimate. The result of the quark model and of recently performed Bethe-Salpeter studies are not (necessarily) in conflict and can be understood as two different approaches toward the description of the same quark-antiquark resonances.
