Beyond the Desert 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).
