The nucleon structure via proton-antiproton annihilation. Meeting GDR PH-QCD Groupe 2: Scattering and annihilation electromagnetic processes

3 oct. 2011, 09:30 → 5 oct. 2011, 17:30 Europe/Paris

Salle des Conseils (IPN Orsay)

Egle Tomasi-Gustafsson (IPN Orsay), Helene Fonvieille (LPC Clermont-Ferrand)

In frame of the activity of the Groupe 2 (http://lpsc.in2p3.fr/GDR-PH-QCD/PEL.html) this meeting aims to gather experimentalists and theoreticians around the following subjects: - Study of the reaction pbar p =>l+ + l- (l=lepton) (radiative corrections, effects induced by the lepton mass on observables...) - the reaction pbar p =>e+ + e- +pi0 (extraction of form factors, TDA, reaction mechanisms) - the reactions e++e- => p+pbar et n+nbar, J/psi production.. - first data from BES - nucleon models - ... The mornings will be dedicated to talks, the afternoons to working groups, round tables and discussions on concrete developments.
