Review on dynamically generated resonances

TL;DR

This paper reviews recent theoretical results on dynamically generated resonances from vector meson interactions with vector mesons and baryons, identifying multiple new states through a unitarized approach.

Contribution

It provides a comprehensive analysis of resonance generation using hidden-gauge Lagrangians, revealing new states in vector-vector and vector-baryon interactions.

Findings

11 vector-vector resonances generated

9 vector-baryon octet states generated

10 vector-baryon decuplet states generated

Abstract

We present recent results on the vector meson-vector meson and vector meson-baryon interaction using a unitary approach based on the hidden-gauge Lagrangians. For the vector-vector case we find that 11 states get dynamically generated, corresponding to poles of the scattering matrices on the second Riemann sheet. In the vector-baryon sector we also find 9 states dynamically generated from the vector-baryon octet interaction and 10 from the vector-baryon decuplet interaction. We also report on baryon states found from the interaction of two mesons and a baryon.
