Report on the High Energy Phenomena Sessions HE 2, HE 3.2-3.4: Neutrinos and Muons. Interactions, Particle Physics Aspects, Astro-Particle Physics and Cosmology

The results presented at the 28th International Cosmic Ray Conference on neutrino and muon physics are summarized. Neutrinos and muons provide a huge amount of information on particle interactions up to very high energies and on fundamental particle properties. Results on neutrino oscillations in the atmospheric and solar neutrino sectors are summarized. Oscillations are well established in both sectors, and a more precise determination of oscillation parameters is requested in the next future. Neutrino telescopes taking data and under construction presented numerous results. Neutrinos as probes of the Universe are hopefully going to open, together with gravitational waves, a new era for Astrophysics. Cosmology has entered the precision era and the Dark Matter quest is still an open problem. Direct and indirect searches are complementary approaches to the problem. The results presented at this conference confirm that Astroparticle Physics and, in particular, Neutrino Physics are leading fields in fundamental research.
