In this paper, the authors present a detailed description of the physics that can be addressed through N* structure studies in exclusive meson electroproduction, including recent advances in reaction theory for extracting N* electrocouplings from meson electrodes.
Abstract
Studies of the structure of excited baryons are key factors to the N* program at Jefferson Lab (JLab). Within the first year of data taking with the Hall B CLAS12 detector following the 12 GeV upgrade, a dedicated experiment will aim to extract the N* electrocouplings at high photon virtualities Q2. This experiment will allow exploration of the structure of N* resonances at the highest photon virtualities ever achieved, with a kinematic reach up to Q2 = 12 GeV2. This high-Q2 reach will make it possible to probe the excited nucleon structures at distance scales ranging from where effective degrees of freedom, such as constituent quarks, are dominant through the transition to where nearly massless bare-quark degrees of freedom are relevant. In this document, we present a detailed description of the physics that can be addressed through N* structure studies in exclusive meson electroproduction. The discussion includes recent advances in reaction theory for extracting N* electrocouplings from meson electropro...

Understanding the nucleon as a Borromean bound-state

TL;DR: In this article, it was shown that the nucleon may be understood primarily as a Borromean bound-state, in which binding arises mainly from two separate effects: strong running coupling and quark exchange.

Strong QCD from Hadron Structure Experiments

TL;DR: The 2019 Strong QCD from Hadron Structure Experiments Workshop as mentioned in this paper aimed to develop plans and facilitate the future synergistic efforts between experimentalists, phenomenologists, and theorists working on studies of hadron spectroscopy and structure with the goal to connect the properties of hadrons and atomic nuclei available from data to the strong QCD dynamics underlying their emergence from QCD.

Structure of the nucleon’s low-lying excitations

TL;DR: In this article, a comparison of the four lightest (1/2,{J}^{P}=1/{2}^{\ifmmode\pm\else\textpm\fi{}})$ baryon isospin doublets is performed to elucidate their structural similarities and differences.

The Large N limit of superconformal field theories and supergravity

TL;DR: In this article, it was shown that the large-N limits of certain conformal field theories in various dimensions include in their Hilbert space a sector describing supergravityon the product of anti-de Sitter spacetimes, spheres, and other compact manifolds.

Dynamical Model of Elementary Particles Based on an Analogy with Superconductivity. II

TL;DR: In this paper, a superconductive solution describing the proton-neutron doublet is obtained from a nonlinear spinor field Lagrangian, and the pions of finite mass are found as nucleon-antinucleon bound states by introducing a small bare mass into the Lagrangians which otherwise possesses a certain type of the ∆-ensuremath{gamma{5}$ invariance.
