Description

Our main objective in this workshop  is to discuss in an informal interactive format the two-pion and e+e- production in pp and pi p reactions in connection with the interpretation of HADES data and the preparation of new experiments at GSI and  FAIR,

In particular, the following subjects will be addressed

  • Baryon spectroscopy ( e.g. 2piN branching ratios from PWA of pion beam together with photon beam,  cascade resonances, triangular singularities,......)
  • Rho contribution ( direct production and production via resonances,   check of Vector Dominance for baryons )
  • Time-like electromagnetic form factors
  • Nucleon-Nucleon reaction mechanisms (single/double baryon resonance contributions, meson production)
  • Search for dibaryons (consistency of the measurement in different decay channels,...)
  • Impact for medium effects study

 

Preliminary list of speakers and topics:

  • Amel Belounnas (IPN Orsay) :HADES results for the pp->pppi+pi- reaction at 3.5 GeV.
  • Mikhail Bashkanov (Edinburgh University) electro-magnetic properties of the d* dibaryon
  • Xu Cao (CAS Lanzhou) Lagrangian models for two pion production.
  • Izabela Ciepal (UJ Cracow) event generator for pi-p->ne+e- reaction.
  • Tetyana Galatyuk (TU Darmstadt) e+e- production in heavy-ion reactions: HADES data
  • Malgorzata Gumberidze (GSI Darmstadt)  HADES results for the pp->pppi+pi- reaction at 1.25 GeV incident beam energy.
  • Georgy Kornakov (GSI Darmstadt) HADES results concerning baryon resonances in medium
  • Alexander Jerusalimov (JINR Dubna) OPER model for multipion production.
  • Gennady Lykasov (Dubna) remotely phenomenology of pion beam experiments
  • Stefan Leupold (Uppsala) Models for hyperon electromagnetic form factors
  • Victor Mokeev (Jlab, USA) remotely: results form two-pion production in electron scattering experiments
