Dynamically generated hadron resonances

TL;DR

This paper explores how certain hadron resonances are dynamically generated through vector meson-baryon interactions, predicting new states and analyzing their decay widths using the local hidden gauge formalism and Faddeev equations.

Contribution

It introduces a comprehensive approach to dynamically generate hadron resonances, including predictions for new states and decay properties, using advanced theoretical frameworks.

Findings

Many resonances match known states

Predicted new resonances not yet observed

Decay widths analyzed for pseudoscalar baryon channels

Abstract

As an example of dynamically generated resonances we mention the interaction of vector mesons with baryons within the local hidden gauge formalism which gives rise to a large amount of such states, many of which can be associated to known resonances, while others represent predictions for new resonances. The width of these states coming from decay into pseudoscalar baryon is also addressed. We also mention recent states coming from $\Delta \rho \pi$ interaction obtained with Faddeev equations.
