Muons and neutrinos

This report reviews several selected topics presented in SH1.01 and HE2.01 – HE2.06 sessions dedicated to muons and neutrinos. There were 118 papers in these sessions. Many of them deserve discussion and presentation in rapporteur talks. However, I put the priority to exciting new results, primary the results on neutrino oscillations from solar and atmospheric neutrinos. The first results from the SNO experiment combined with the Super-Kamiokande solar neutrino data give essential information toward the understanding of the 30-year-old “solar neutrino problem”. Increased statistics of the atmospheric neutrino data make it possible to study details of muon neutrino oscillations. Recent precise atmospheric muon data give very important constraint to the absolute flux of the atmospheric neutrinos. The results from recent muon measurements are reviewed and the status of the new generation oft he neutrino flux calculations is summarized. Finally, status and the future prospect of the high energy neutrino astronomy are discussed.
