SCHMITZ G RAFFELT & N SCHMIT B A KNIEHL - Böcker

This volume constitutes the proceedings of the Ringberg Euroconference, which brought together 44 experimental and theoretical physicists from all over the world who are actively working in neutrino physics and in closely related fields. The purpose of the meeting was to communicate the latest experimental results and to exchange new theoretical ideas on the phenomenology of neutrinos within and beyond the standard model of particle physics, as well as in astrophysics and cosmology.Results from past and present laboratory experiments were presented at the conference, and they have yielded valuable information; continuation of such experiments and future new experiments may bring us closer to some sought-after answers. In astrophysics, the most exciting results come from Superkamiokande and refer to solar neutrinos, bringing the problem of the solar neutrino deficit closer to a solution, and to atmospheric neutrinos, indicating that the neutrinos apparently do have a non-zero mass. Decisive new results are expected from new running and new forthcoming detectors. In theory, much attention has been devoted to constructing scenarios which explain the apparently large neutrino mixing angles. In cosmology, neutrinos may play a crucial role for baryogenesis, and may contribute a hot dark matter component beyond cold dark matter, which apparently dominates the mass density of the universe. The hypothesis of a hot plus cold dark matter cosmology may be tested with the forthcoming MAP and PLANCK cosmic microwave background missions and large scale galaxy surveys such as the Sloan Digital Sky Survey. This short overview shows the present liveliness of neutrino physics and the bright prospects in the field.
