Beyond the Desert 2003 Proceedings of the Fourth Tegernsee International Conference on Particle Physics Beyond the Standard BEYOND 2003, Castle Ringberg, Tegernsee, Germany, 9–14 June 2003

The Fourth International Conference on Particle Physics Beyond the Standard Model (BEYOND THE DESERT '03 - Accelerator, Non-accelerator and Space Approaches) was held during June 9-14, 2003 at Castle Ringberg, Tegernsee, Germany. Traditionally the Scientific Program of the BEYOND conferences, which we started in 1997, covers most of the prominent topics of modern par ticle physics and astrophysics (see CERN Courier November 1997, pp. 16-18, and March 2003, pp. 29-30). At this conference one of the topics on which we put major emphasis were new theoretical developments in extensions of the Stan dard Model by Supergravity - which had its twentieth birthday in this year -, by Superstrings and by Extra Dimensions. Two of the 'inventors' of the first superspace formulation of supergravity - Pran Nath and Richard Arnowit- were participants at this meeting. These topics were discussed by Pran Nath (Boston), Dick Arnowitt (Texas A&M) - who concentrated on the connection to dark matter and g-2 of the muon -, A. E. Faraggi (Oxford, UK), R. E. Allen (Texas A&M) and A. Kobakhidse (Helsinki Univ. ). Fundamental symmetries, including CP violation beyond the Standard Mo del, a possible time variation of the QCD scale, and the status of preons, were dis cussed by Peter Herczeg (Los Alamos), M. N. Rebelo (Lisboa, Portugal), R. Leh nert (Algarve Univ., Portugal), Harald Fritzsch (Munich) and S. Fredriksson (Lulea Univ., Sweden)."
