        20th INTERNATIONAL WORKSHOP ON WEAK INTERACTIONS AND NEUTRINOS 
                                                                          
      (WIN'05) 
                                             
      June 6-11, 2005,   DELPHI, GREECE 
       
      Dear Colleague, 
       
      The 20th International Workshop on Weak Interactions and Neutrinos will take place at the European
      Cultural Center, in Delphi, Greece, from June 6-11, 2005. This is a workshop with a small number of
      participants (about 100 physicists), which has a history of about 30 years. Previous WINs have taken place in Europe, Asia,
      New Zealand,
      Africa, and USA, with the last one, WIN03, in Lake Geneva, Wisconsin, USA. 
       
      The purpose of the workshop is to offer the physics community a  significant opportunity to assess the status of the field and
      initiate collaborative efforts to address current physics questions.  
       
      There will be four working groups with the following themes for WIN05: 
       
                             
      Working Group 1 - Electroweak Symmetry Breaking 
                             
      Working Group 2 - Weak Decays, CKM Matrix, CP Violation 
                             
      Working Group 3 - Neutrino Physics 
                             
      Working Group 4 - Astroparticle Physics 
       
       
      The Local preparations are well under way and we expect to open the registration soon. A poster will be ready to be distributed at the
      end of next week. 
       
      There is a continuously updated website at:

       We plan the following structure of the program:

      Afternoon:  Transportation to Athens 
       
      Following introductory plenary status reports the working groups will devote two and a half days discussing the issues with emphasis on current
      problems of interest. We plan an additional half day or so of plenary  
      talks on Friday afternoon for topics of current interest, and on Saturday we shall have the Summary talks from the working groups.
      Besides reviewing the status of the field and addressing current issues,  
      the purpose of the workshop is to establish research projects which may continue beyond the Workshop.  
       
      The Program Committee is currently working on the selection of the plenary speakers and the working group convenors.  Once this is
      finished, we shall inform you via the WEBsite and also with another Bulletin. 
       
      Please stay tuned! 
       
     Best Regards, 
       
      For the WIN'05 Organizing Committees,
