PHENOMENOLOGY OF UNIFICATION FROM PRESENT TO FUTURE

The conference reviews the results obtained so far, and the perspectives in the foreseeable future concerning unification of the forces and laws of nature.One of its important features is the emphasis on phenomenological implications of the different theoretical approaches reviewed by invited speakers, keeping in view possible experimental tests to be made with the technologies now available or to be developed in the future.The first part of the proceedings covers unification problems connected with the electroweak theory and the standard model, the so-called "grand" unification and the supersymmetry. The surveys of the experimental data available are from LEP accelerator experiments, the physics at LHC (Large Hadron Collider), as well as CP violation, neutrino oscillations, and proton decay.Following these are surveys of the perspectives of future high energy accelerators, like the LHC at CERN, the electron-positron colliders, and the possible new acceleration methods.The second part of the proceedings concerns the more advanced problems of the unification of gravity with the other forces of string theory and quantum gravity, with the interesting phenomenological implications concerning cosmology and quantum mechanics.The implied phenomenology is presented and discussed at two fundamental levels: testing the quantum mechanics at a macroscopic level, with special measurements of superconducting quantum states, and possible detection of classical and quantum features of gravitational radiation, not only from astrophysical sources but also from possible laboratory sources.Finally, the perspectives of fundamental physics are discussed.
