  51. 5. $\Lambda^*$ and $\Sigma^*$ spectrum from the Jülich-Bonn DCC model
    Deborah Rönchen

    The Jülich-Bonn model is a well-established dynamical coupled-channel approach that has been applied in recent years primarily to study the spectrum of light baryon resonances from pion- and photon-induced reactions with different hadronic final states. In this talk, I will present the adaptation of the framework to kaon-induced reactions with the goal to extract the spectrum of resonances...

  52. 70. Baryon structure from lattice QCD
    Sara Collins

    Through the calculation of nucleon matrix elements both in
    the forward and off-forward kinematics using lattice QCD, a wealth of
    information on the structure of the nucleon can be accessed. This
    includes the determination of the electromagnetic form factors, the
    axial form factors, moments of (generalised) parton distribution
    functions and includes the gravitational form factors....

  53. 64. Chiral dynamics and the Delta resonance
    Evgeny Epelbaum

    We review the formulations of chiral effective field theory with explicit Delta degrees of freedom and discuss the role of the Delta isobar in low-energy reactions involving pions, nucleons and photons. Topics considered include pion-nucleon scattering, pion photoproduction, Compton scattering as well as parity-conserving and parity-violating nuclear interactions.

  54. 65. Complementary insights into the pseudoscalar meson and baryon structure from AMBER
    Dr Oleg Denisov (INFN-Torino)

    It is quite evident that in order to shed a light on Emergence of Hadron Mass phenomenon it is not enough to deeply study the proton structure but to know much more about pseudoscalar mesons and excited baryons and their properties. A lack on knowledge in this field is quite justified by the fact that it is much more difficult to study properties of unstable particles (i.e. mesons and excited...

  55. 6. Dispersive and model-independent extraction of baryon resonances from pion-nucleon total cross-section data
    Mr Pablo Rabán (Universidad Complutense de Madrid)

    A precise description of low-energy $\pi N$ interactions and the lightest baryon spectrum is essential for many problems in hadronic and nuclear physics. Following a careful revision of the database, we determine $\pi N$ resonance parameters from forward dispersion relations using exclusively total cross-section data together with the optical theorem.

  56. 2. Electroproduction of Cascade Hyperons using CLAS12 at Jefferson Lab
    Bianca Gualtieri (Florida International University)

    Cascade hyperons, despite being discovered over half a century ago, remain considerably less studied compared to the non-strange $\Delta$ and $N$ baryons. The objective of this analysis is to provide cross-section measurements for the ground state cascade, $\Xi^-(1320)$ and $\Xi^-(1530)$ , using electron beam energies of $6.5$ and $7.5$ GeV. These measurements span both the quasi-real...

  57. 66. Emergence of mass in the gauge sector of QCD.
    Joannis Papavassiliou

    It has long been argued that the action of the Schwinger mechanism in the gauge sector of Quantum Chromodynamics leads to the generation of a gluon mass scale. Within this scenario, the analytic structure of the fundamental vertices is modified by the creation of scalar colored excitations with vanishing mass. In the limit of zero momentum transfer,
    these terms act as massless poles,...

  58. 62. Exotic hadrons: Review and perspective
    Qian Wang (South China Normal University, Guangzhou, China)

    Thanks to the increasing statistics of experimental data, numerous exotic candidates have been observed, such as the famous X(3872), the double charm tetraquarks, and so on In this talk, I will briefly review the current status of the study of these exotic hadrons, with a particular focus on new methods that have the potential to advance current research, such as machine learning approaches...

  59. 68. Experiment –Exploring baryon resonances with transition generalized parton distributions: status and perspectives
    Dr Stefan Diehl (Justus Liebig University Giessen and University of Connecticut)

    QCD provides a rich spectrum of excited baryon states. The understanding of their internal structure is of essential important for many fields of nuclear physics, such as nuclear forces, dense matter or neutrino-nucleus interactions. It is known, that Generalized Parton Distributions (GPDs) are a well established tool for characterizing the QCD structure of the ground-state nucleon based on 3D...

  60. 71. General Hamiltonian Approach to the N-Body Finite-Volume Formalism
    Jia-jun Wu

    We present a nonperturbative Hamiltonian framework (NPHF) to address the general N-body problem. This framework rigorously connects finite-volume spectra from lattice QCD to scattering observables from experiment. Here we will present the several example to show how to use our method to extract omega from pipipi lattice spectrum.

  61. 1. Global Extractions of 12C, 40Ca and 56Fe Nuclear Electromagnetic Response Functions and Comparison to Theory and Neutrino/Electron MC Generators
    Arie Bodek (University of Rochester (US))

    We have performed a global extraction of the 12C, 58Ca and 56Fe longitudinal (RL) and transverse (RT) nuclear electromagnetic response functions from an analysis of all available electron scattering data on these nuclei. The response functions are extracted for energy transfer spanning the nuclear excitation, quasielastic (QE), resonance and inelastic continuum over a large range of the...

  63. 3. New electron-scattering pion-production constraints for neutrino event generators
    Julia Tena Vidal (Universitat de València)

    A major challenge for neutrino oscillation experiments, which rely on wide-band fluxes, is the accurate reconstruction of neutrino energy from observed final-state particles. This reconstruction depends on nuclear and interaction models embedded in event generators, which are limited by underlying assumptions and must be constrained by external data. Electron scattering experiments, which use...

  64. 4. Nucleon Resonance Studies from Exclusive KY Photo- and Electroproduction
    Daniel Carman (Jefferson Laboratory)

    Studies of the spectrum and structure of excited nucleon ($N^*$) states via photo- and electroproduction of exclusive reactions are important for exploring non-perturbative strong interaction dynamics. Data from the $KY$ channels is complementary to studies limited to the non-strange $\pi N$, $\eta N$, and $\pi \pi N$ channels. $KY$ photoproduction observables have been pivotal in identifying...

  65. 7. Odd parity nucleon and hyperon resonances
    Zhan-Wei Liu (Lanzhou University)

    We have studied nucleon and hyperon resonances based on the experimental scattering data and lattice QCD simulations within Hamiltonian effective field theory. Some of them are very exotic, for example, the is mainly a molecule and the is dynamically generated. However, the traditional triquark states are still very important and exist in the excited baryons, for example, the contains the...

  66. 10. Predictions of $N^*$ effects on the $\pi N\to \pi\pi N$ reactions within the ANL-Osaka Model
    tsung-shung Lee (Argonne National Laboratory)

    Using the Argonne National Laboratory-The University of Osaka (ANL-Osaka) DCC model
    of meson-nucleon reactions, we predict the cross sections of
    the $\pi N \to \pi \pi N$ reactions.
    The model was constructed by fitting
    only the two-body reactions:
    $\pi N,\gamma N \to \pi N, \eta N, K\Lambda, K\Sigma$.
    Thus, the results for $\pi N \to \pi \pi N$ presented here
    are predictions of the...

  67. 67. Studies of N* and Delta* in pi N --> pi pi N reactions at J-PARC
    Dr Hiroyuki Sako (Japan Atomic Energy Agency)

    Although nucleon resonances (N and $\Delta$) have been studied for a long time, there are still many resonances which have not been established experimentally, which were measured mostly using $\gamma N\rightarrow \pi N$. $\pi N \rightarrow \pi N$, and $\gamma N \rightarrow \pi\pi N$ data. On the other hand, there are only a limited number of events of $\pi N \rightarrow \pi\pi N$ data,...

  68. 8. Systematic account of bound-state motion for high precision studies.
    Alexander Kvinikhidze (A. Razmadze Mathematical Institute of the Tbilisi State niversity)

    In the talk a missing part of the extensively used chiral effective field theories is presented which is necessary for accurate study of the processes involving
    bound states.

    Contemporary high precision experimental studies of the processes where bound states are involved open the possibility of the accurate study of their characteristic features. To maximise the
    accuracy the...

  69. 60. The behavior of the deuteron within a hadronic environment
    Prof. Luciano Melo Abreu

    We study deuteron interactions with light mesons in the hadronic phase of heavy-ion collisions. Treating the deuteron as a weakly bound state, we use the quasi-free approximation for the $d\pi$ interaction. The elementary $N\pi$ amplitudes are described by an effective model that combines the non-resonant background from chiral perturbation theory with resonant contributions parameterized by...

  70. 9. The N* Electroexcitation and Strong QCD from the Data of Experiments at JLab
    Victor Mokeev (Thomas Jefferson National Accelerator Facility)

    Analyses of exclusive meson electroproduction data obtained with the CLAS detector at Jefferson Lab have provided the only information on the evolution of the nucleon resonance (N) electroexcitation amplitudes—known as the γ pN* electrocouplings—over the mass range up to 1.75 GeV for photon virtualities from the photon point up to Q² = 5.0 GeV². Recent advances in these studies and their...

  71. 63. The quark model of baryons
    Jean-Marc Richard (University of Lyon & CNRS-IN2P3, France)

    We review the constituent quark model of baryons, as developed in the 1960s by Greenberg and by Dalitz and his collaborators and successors, notably Isgur and Karl, and discuss how this framework can be related to the underlying quark dynamics. We briefly address several developments beyond the simple harmonic-oscillator model, including certain mathematical aspects of the three-body problem...

  72. 61. Towards a theory of hadron resonances
    Maxim Mai (University of Bern)

    What are the mechanisms behind the labyrinthine spectrum of excited hadrons? This question challenges our understanding of strong interaction and is of relevance to many applications where the exact parameters of these states influence interaction patterns.

    To uncover this riddle a synergetic combination of available analytical (EFT's, S-Matrix...), Numerical (Lattice QCD), or...
