Agenda for Lambda meeting, DESY, Febr.22-24, 2005

Tuesday,  Febr. 22, 2005  13:00 -19:00  1b/4a

General discussion"Present and Future  of   
Hyperon Physics at HERMES"        
   
n1   Semi-inclusive L production    *What can we learn from L and antiL
                                                       polarization in target and current fragmenatation regions?
                                                       Interpretation of HERMES results  presented  in draft_20/*

n2                                                  *How usefull might be the polarized target
                                                        data, not included yet in the  analysis?*
                                      
n3   Exclusive strangeness               *What can we learn from gamma+p->L+K or \Sigma+K
       production using  RD+LW         exclusive channels?*  
                               
n4                                                  *Nuclear effects with strangeness* (optinal)

n5  Hyperons at  HERMES and      *HERMES,COMPASS,JLAB,SLAC,RIHC,...* (optinal)
      at other experiments

Wednesday,  Febr. 23, 2005   09:00 - 13:00      1b/4b
                                                 13:00 - 20:00       1b/5

General discussion (continuation)

n6  Semi-inclusive                      *Study of unpolarized strangeness production,
      unpolarized                            multiplicities, fragmentation funtions,P-T dependence,
                                                   L/Lbar yields etc.
                                                   Comparison with MC.
                                                   Can we specify  strangeness production mechanism?*                            

n7  DSA                                    * DSA in semi-inclusive strangeness production,
                                                     what this analysis aimed at?*                                                  
                                       
n8  Photo-production                * Possible mechanisms of transverse L,Lbar polarization*
                             
n9                                             *Longitudinal spin transfer in  photoproduction. Is it related to
                                                  gamma->ssbar splitting?*
                                       
n10                                           * Yields and cross-sections  for hyperon production,
                                                    MC tune, what else ...?*
