3 TentaFve Structure IntroducFon TheoreFcal framework (Nora Brambilla) Hadron Spectroscopy (Dave Ireland) Hadron Structure (Nicole D Hose) Hadronic InteracFons (Andrzej Kupcs) RecommendaFons 3

4 SubsecFon: TheoreFcal Framework Topics: Tools: QCD, effecnve field theories, models, S-matrix theory, funcnonal methods Interplay between la8ce QCD and EFTs Rôle of symmetries Confinement mechanism exp. studies of hadronisanon, QGP Hadronic matrix elements: QCD factorisanon, la8ce QCD Hadron resonances: theorencal interpretanon; ab inino studies QuanNfy hadronic uncertainnes in precision observables work towards precision era of hadron physics Strongly interacnng systems and muln-scale problems Anomalies, axions 4

5 SubsecFon: Hadron Spectroscopy Topics Charm and bo-om spectroscopy: X, Y, Z states, pentaquarks (Experiments: BES-III, PANDA, LHC-b, ATLAS, CMS, Belle) Light quark spectroscopy, including exoncs and glueballs (Experiments: COMPASS, JLab, PANDA) InterpretaNon: PWA, stansncal analysis methods (MEM, inference methods, ); reduce model dependence in interprenng experimental data Isospin breaking 5

6 SubsecFon: Hadron Structure Recent achievements / current status Proton radius puzzle: ep sca-ering, atomic physics & laser spectroscopy Electromagne5c form factors: role of two-photon processes GPDs, PDFs, TMDs: Data analysis, theorencal interpretanon, role of hadron beams; relevance of PDFs for LHC Polarisabili5es: experimental determinanons and tests of theorencal formalisms Future direcfons GPDs, PDFs, TMDs: connnuanon of current program Form factors: Nmelike regime; strangeness form factors 6

7 SubsecFon: Hadronic InteracFons Topics MulN-hadron systems; hadronic molecules; hypernuclei Study ππ, πn, NN, πh, NH interacnons; van der Waals interacnons Tools: PWA, NN potennals from EFT perspecnve (2- and 3-body forces, ) (clarify overlap with WG3 Nuclear Structure) 7

8 Issues to be discussed LaDce QCD and compufng Also relevant for WG2 (Phases of Strongly InteracNng Ma-er), WG3 (Nuclear Structure and Dynamics), WG5 (Fundamental InteracNons) World-wide effort towards exascale compunng; corresponding recommendanons in the US LRP Calls for a more general discussion / presentanon within the LRP; could add appropriate boxes Searches for new light parfcles; New Physics What is the appropriate secnon for new light parncles searches ( dark photons, axions, ) More general issue: experimental techniques originate from hadron physics 8

9 Issues to be discussed FaciliFes (in Europe and elsewhere) FAIR: PANDA, HESR (status implicanons from Heuer Report ) Prospects for IKP@FZ Jülich implicanons for HESR, pedm CERN: COMPASS, ALiCE Lepton beams: DAPHNE, ELSA, MAMI, MESA, S-DALINAC Electron-Nucleon / Electron-Ion Collider Polarised proton annproton beams; LHeC 9

10 RecommendaFons PrioriFes in Hadron Physics from LRP 2010 I. Speedy construcnon of II. Complete and exploit current facilines to ensure a-racnve research opportunines prior to complenon of FAIR III. ConNnued support for theory IV. Upgrade of HESR into proton annproton collider 10
