DESCRIPTION:Speakers: Jorge Segovia (U. Pablo de Olavide\, Seville)\, Feli
 ciano De Soto\, José Rodríguez-Quintero\, Adnan Bashir\, Guillermo D. Me
 gías\, Juan A. Caballero\n\n\nNSTAR 2026\nThe 15th International Workshop
  on the Physics of Excited Nucleons will take place in Seville from  Sep
 tember 7th to 11th\, 2026.\nNucleon excitations are providing a unique opp
 ortunity to explore many facets of the non-perturbative strong interaction
  and how various baryons\, including those with strange and heavy flavor c
 ontent\, emerge from Quantum Chromodynamics (QCD)\, the Poincaré invarian
 t quantum non-Abelian gauge field theory that describes the strong-intera
 ction part of the Standard Model of Particle Physics. The rapid growth of 
 high-quality experimental results on exclusive meson photoproduction off n
 ucleons from CLAS\, ELSA\, GRAAL\, LEPS\, and MAMI allow us to pin down re
 action amplitudes with unprecedented precision and to establish the baryon
  spectrum with minimal model dependence. Experiments with hadronic beams (
 GSI\, JPARC) and hadron production in e+e- collisions (BES) extend and co
 mplement the scope of baryon spectroscopy\, where the importance of baryon
  states in the evolution of the Universe has also just recently been eluci
 dated.\nSpace-like resonance electrocouplings can be extracted\, based mai
 nly on the CLAS data on exclusive meson electroproduction off nucleons\, o
 ver a wide range of photon virtualities and provide valuable information o
 n the excited nucleon structure by offering access to non-perturbative str
 ong interaction mechanisms behind the N* generation. The insight into the 
 baryon structure is complemented by the studies of time-like form factors 
 (BABAR\, BES\, GSI\, PANDA).\nFrom the theory side\, Dyson-Schwinger-Equat
 ions and Lattice-QCD functional approaches are remarkably progressing in d
 escribing the baryon spectrum and structure from the first principles of Q
 CD. New opportunities to explore the full spectrum of excited nucleons\, s
 trange and heavy baryons as well as exotic multiquark structures in the ba
 ryon sector have been offered by advances in QCD-inspired quark models. In
  addition\, effective field theories\, such as chiral perturbation theory\
 , provide valuable low-energy benchmarks and constraints that complement f
 irst-principle methods. Light-front holography and AdS/QCD models have ope
 ned alternative pathways to connect hadron spectroscopy with underlying QC
 D dynamics\, while QCD sum rules continue to serve as a bridge between non
 -perturbative QCD and phenomenology. Moreover\, coupled-channel dynamical 
 models contribute providing essential insights into hadron scattering and 
 decay properties. Taken together\, this broad theoretical toolkit offers a
  comprehensive framework to deepen our understanding of baryon structure a
 nd spectrum.\nSynergistic efforts between experimentalists and theorists h
 ave already demonstrated our capability to address some open key problems 
 of hadron physics on the nature of hadron mass\, quark-gluon confinement\,
  dynamical chiral symmetry breaking\, and their emergence from QCD. The pu
 rpose of this workshop is to share the latest results on various aspects o
 f low-energy QCD dynamics in terms of nucleon excitations and baryon reson
 ances\, and to discuss the future developments.\nTopics covered in the wor
 kshop are:\n\nBaryon spectrum through meson photoproduction.\nBaryon reson
 ances in experiments with hadron beams and in the e+e- collisions.\nBaryon
  resonances in ion collisions and their role in cosmology.\nBaryon structu
 re through meson electroproduction\, transition form factors\, and time-li
 ke form factors.\nAmplitude analyses and baryon parameter extraction.\nBar
 yon spectrum and structure from first principles of QCD.\nAdvances in the 
 modeling of baryon spectrum and structure.\nFacilities and future projects
 .\nOther topics related to N* physics.\n\n\nhttps://indico.global/event/15
