  19. Project PAX Collaboration PAX proposed experiments with polarized antiprotons. For this a dedicated facility at FAIR to polarize an antiproton beam could be built. Scientific program:studies in the field of high energy spin physics with use of apolarized antiproton beam Main goal:measurement of thetransversitydistribution,the last missing piece of the QCD description of partonic structure of the nucleon. Transversity describesdistribution of transversely polarized quarks inside the transversely polarized nucleon. Unlike the well-known unpolarized distributionq(x,Q2) and partlyknown helicity distributionDq(x,Q2), transversityhq1(x,Q2)has never been directly measured. Transversity distribution is directly accessible uniquely via the double transverse spin asymmetryATTin the Drell-Yan production of lepton pairs: phphgl+l-X Transversity via single-polarized and unpolarized DY processes (LPP) ! Other topics:electromagnetic form factors (phases in the timelike region, GE-GM separation, …) single-spin asymmetries (Sivers and Collins mechanisms, …) p-pbar hard scattering mechanisms

  36. JINR STC(15 May 2007)- Recommendations • In the updated Road Map, balance JINR participation in the international projects realized outsideandinside JINR giving more weight to the latter (e.g. NICA). Stimulate the participation of young scientists in the home projects. • Consider CERN and GSI as basic JINR partners in PP & RNP. Use the participation in the ambitious projects outside JINR for realization of highly competitive scientific goals as well as a way to support high qualification of JINR staff. • Participate only in the most ambitious outside projects. Use essential part of the financial resources to guarantee the effective work within these projects basically in Dubna and thus make the work here attractive for young scientists from JINR member states.
