In order to connect predictions for the baryon spectrum from quark models or lattice calculations to experimental data, coupled-channel frameworks are especially suited. In those approaches a simultaneous partial-wave analysis of multiple reactions with different initial and final states is performed.
I will present recent results from the Juelich-Bonn dynamical coupled-channel approach,...
The study of the spectrum and structure of excited nucleon (N∗
) states via the electroproduction of exclusive reactions is an important avenue for exploring the nature of the non-perturbative strong interaction. The $\gamma_vpN^*$ electrocouplings of N∗ states in the mass range below 1.8 GeV have been determined from analyses of CLAS $\pi N$, $\eta N$, and $\pi\pi N$ data at beam energies up...
The study of the nucleon structure and of its excited states
is a powerful tool in order to gain a better understanding
of the dynamics inside the nucleon and of the non-perturbative regime of QCD.
The different observables accessible using polarized photon
beams and/or polarized nucleon targets play an essential role
in this experimental research due to their enhanced sensitivity...
High-energy electrons and photons are a remarkably clean probe of hadronic matter, essentially providing a microscope for examining atomic nuclei and the strong nuclear force. One of the most striking phenomena of Quantum Chromodynamics (QCD) is the formation of the nucleon out of massless gluons and almost massless quarks. This system of confined quarks and gluons serves as the basic...
The idea of dressing quark-model states in a coupled-channel analysis to describe scattering data has been around for decades. What’s new are formalisms able to bring these descriptions to the finite-volume of lattice QCD where calculations of the excitation spectrum provide new constraints. This combination of lattice QCD and experiment demands that we reconsider our preconceived notions...
Why nucleon resonance excitations play a unique role in leading the path towards a comprehensive QCD theory will be laid out and illustrated by recent exclusive meson electroproduction results off free and bound nucleons. Near- and potential long-term achievements will highlight upcoming opportunities.
Hadron spectroscopy is a field of considerable interest for validating predictions of the Heavy Quark effective theory and calculations of Lattice QCD at low energies. LHCb has been the main player in the field, having observed more than 50 new hadrons, both conventional and exotic. This talk will present new exciting results released by LHCb recently. On the one hand, for conventional...
In this talk we will give a general overview on recent results from several groups
on the spectrum and properties of light baryons as obtained in the framework of
Dyson-Schwinger and Bethe-Salpeter equations.
We will discuss the spectrum of light baryons with focus on the comparison with
quark model expectations and explain the importance of relativistic components
in the wave...
