Final Activity Report Summary - FORCESUNIVERSE (Constituents, fundamental forces and symmetries of the universe)

Members of the network made substantial progress in the understanding of the fundamental constituents of matter and their interactions. New symmetry structures were discovered and discussed. In particular, it was shown that the strong gauge interactions among quark like particles can be equivalently described by gravitational interactions in spaces, where one space dimension is added. This is the holographic principle, which states that many aspects of our worlds can be projected down from a theory in higher dimensions. This happens to be true in string theory, and hence string theory as a unified theory of all matter and interactions was investigated.

String theory is a theory in ten space-time dimensions. It was shown that in string theory together with new membrane-like objects and by curling up six extra dimensions many features of our world like the existence of quarks and electrons and their interactions can be obtained (the standard model of particle physics). In addition it was discussed how string theory can possibly describe the physics of the early universe just after the Big Bang. In all considerations, the symmetry concept of supersymmetry and supergravity played a key role.

It is hoped that supersymmetry can be discovered at the LHC collider machine at CERN during the next years. Furthermore, one even hopes to see some traces of strings at the LHC. These topics were also considered my members of this network. Finally, new quantum aspects of black holes were discovered.
