Abstract
A coupled channel model is used to study the nature of the f0(980) resonance. It is shown that the existence of two poles close to KKbar threshold, as found in many data fits and confirmed here, can be reconciled with the KKbar molecular origin of the f0(980). Due to a strong coupling between channels the number of the S-matrix poles close to the physical region in the physical case exceeds the number of bare states introduced in the model.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.

The chiral unitary approach to hadron dynamics has brought a new perspective to deal with the interaction of hadrons and the nature of some resonant mesonic [ref] and baryonic states [ref] which appear dynamically generated from the interactions and, thus, have a nature quite different to standard $q q̅$ states.

The $ππ$-$KK̅$-$πη$ coupled-channel system around $1$ was studied in this framework in Ref. [ref] with a particular interest in the $f_0$ and $a_0$ resonances followed by the studies with similar approaches [ref] [The scalar mesons around 1 GeV have been studied for a long time, and many studies were devoted for it from various viewpoints, e.g., as done in Refs. [ref] (see also Ref. [ref] for a review article).] and the applications to many reactions.
