  19. Involvement in Neutrino Experiments (with PL affiliation) Neutrino oscillations However the road to additional ICARUS modules appears to be a very rocky one……. Therefore we are using the acquired expertise in LAr technique in simulations forT2K-LAr. We also consider hardware contributions to T2K. Future accelerator long-baseline experiment: T2K Polish neutrino group D. Kielczewska, ApPEC SC

  25. On April 27-28 S. Jullian (NEMO-3 spokesman) and D. Lalanne were in Warsaw to discuss a possibility to join the collaborations. was formed see the presentation by Z. Janas this afternoon D. Kielczewska, ApPEC SC

  27. Theoretical groups closely related to the experimental activities • Neutrino interactions with special attention to nuclear effects for long- baseline accelerator neutrinos. Preparation of MC generator - Wrocław neutrino group (J. Sobczyk) • Neutrino emission from pre-supernova • Of great interest to Super-Kamiokande Collaboration in connexion to a possible upgrade: adding Gd for neutron detection. Purpose – early warning for a SN gravitational collapse • A. Odrzywolek,M. Misiaszek, M. Kutschera(Kraków) • Astroparticle Physics 21 303 (2004); astro-ph/0511555 • Double beta decays W. Kaminski (Lublin) see the presentation on WWW D. Kielczewska, ApPEC SC

  28. PhD theses (since 2002): Completed >6 Current >10 MSc theses (since1998): Completed >20 Topical Neutrino conferences organized in PL: 1. Nuclear effects in neutrino interactions 20th Max Born Symposium, Dec. 7-10, 2005, Wrocław, Poland 2. Cracow Epiphany Conference on Neutrinosand Dark Matter, Cracow, Poland, 5-8 January 2006. D. Kielczewska, ApPEC SC

  29. Summary Strength of experimental neutrino physics in PL: 9 institutions, 39 physicists (18 senior & 21 junior) • We are involved in the most successful neutrino experiments • Elsevier awarded its SCOPUS award for the most cited science papers with Polish authors for publications in neutrino physics • The groups (experimental and theoretical) collaborate very closely - with regular meetings/workshops in Katowice, Kraków, Warszawa or Wrocław.This is very helpful in sharing our expertise in various fields. Our Weakness: my personal view We are involved in too many different projects and our initial plan to unify and to have significant contribution in one attractive experiment has not come to fruition yet. To help that we organize a Polish Neutrino Network this afternoon. D. Kielczewska, ApPEC SC
