Particle Physics and the Universe

(1998, NS 109)
August 20-25, 1998
Haga Slott, Enköping, Sweden
Organizers: Professors Per Carlson, Royal Institute of Technology; and Lars Bergström and Claes Fransson, Stockholm University.

About 50 people participated in the symposium, including 36 invited lecturers from abroad. One major field at the symposium was neutrino physics. New experimental data indicate that the neutrino actually has a non-zero mass. This enables the various neutrinos (there are three different ones) to oscillate between each other by quantum-mechanical means. For example, the excessively low number of observed solar neutrinos can be explained by oscillations. Several contributions dealt with different aspects of neutrino research. Neutrinos with mass may also comprise part of the "dark matter" in the universe. Various methods for studying dark matter were thoroughly discussed. Very high-energy neutrinos can be used to study energy-rich processes at great distances from our own galaxy.

Another highly topical field is the various types of cosmic electromagnetic radiation, ranging from studies of continuous cosmic background radiation to the pulsing sources known as gamma ray bursts. The latter have recently been shown to come from sources outside our own galaxy and are very high-energy. Among the mechanisms suggested are collisions of neutron stars with black holes.

The question of whether the universe will expand eternally or whether its current expansion will be followed by contraction is a very central issue.

The symposium discussed new data from supernova explosions that took place very far away and thus early in the evolution of the universe. The symposium attracted publicity in the press and on radio. Its proceedings have been published in a separate volume of Physica Scripta.
