Hadronic physics Where do we want to go? To do what? Present situation Who and When? Personnel and budget Hadronic physics meeting 19/09/2006 Th. Hennino

Where do we want to go? Concentrate on a limited set of problematics in the future Short term: fulfill our commitments (some weaknesses here and there) Long term future – – JLAB12GeV Hadronic physics meeting 19/09/2006 Th. Hennino

To do what? The structure of hadrons (NUCLEON, baryons, mesons) – At JLAB: GPDs well established experimentally and theoretically – At PANDA Time like form factor (the present hobby-horse) GPDs: new topic under development (french theoretician) Other EM processes transition distribution amplitudes: knowledge is there Hadronic channels (dominate the cross section!) Hadron spectroscopy (completely new field for all of us) – Learning phase – Keep an eye on the running detectors (Babar, Belle, etc..) Hadrons in the medium ( s rest., cf HADES) ?? It is important to strengthen the interaction with theoreticians Hadronic physics meeting 19/09/2006 Th. Hennino

Present situation Constitution of a group at IPN in 2004 (merging forces towards a unique goal: PANDA) Work on PANDA – Physical aspects (physics case still in evaluation process ) p_bar p e + e - (time-like FF) fundamental quantity, feasibility quite challenging p_bar p e + e - X ? Feasibility to be studied Other channels not yet investigated Need for a strong and urgent manpower support – Technical aspects (strong added value work by the Preparation of JLAB12GeV – Physics aspects: continuation of todays activities no major problem to be foreseen – Technical involvement on the CEA side (+ some ideas at IN2P3) IPN (2004) and IN2P3 (2005) scientific councils. Personnel – 2 recent positions given to IPNOrsay (1 at CEA) + 1 (inside) Hadronic physics meeting 19/09/2006 Th. Hennino Tout en appréciant le souci de focalisation manifesté sur PANDA, le CS préférerait donc, pour des considérations de physique, que la possibilité dun programme au JLAB 12 GeV, bénéficiant de limpact que les groupes français y ont acquis, ne soit pas fermée dès maintenant. Il est évident que la communauté de physique hadronique va devenir rapidement sous critique : si cette physique doit se poursuivre et, quelle que soit lorientation finale, il est indispensable que dabord lensemble des physiciens français se regroupe et que quelques embauches soient assurées.

Personnel and budget Future JLAB12GeV – 3.5 CEA + 3 IPNO + 1 LPSC (2 positions) – Technical contribution under consideration PANDA – 2 IPNO + 1 LPCC : insufficient 3 permanent positions + postdocs on a short term (preparation NOW) on a long term for running the experiment – Technical contribution sound evaluation in 2007 budget & manpower request ( ) 5 positions within the next 7 years would be ideal Hadronic physics meeting 19/09/2006 Th.
