Nath Pran Nath – författare

This book contains the proceedings of the Tenth International Symposium on Particles, Strings and Cosmology. About 100 contributions, both theoretical and experimental, presented the latest results in a broad range of topics in astrophysics and cosmology, particle physics and string theory. Topics discussed include reviews of the current status of dark matter; updated experimental results on terrestrial, solar and astrophysical neutrinos; ongoing progress at Fermilab, CERN and underground detectors; electroweak physics; CP, CPT and Lorentz invariance violation; SUSY phenomenology; string theory, string phenomenology and extra dimensions.A companion volume contains about twenty-five talks presented in the Pran Nath Fest held during the symposium to honor Pran Nath on the occasion of his 65th birthday. These talks, presented by renowned theoretical physicists from Dick Arnowitt to Bruno Zumino, cover the range of topics on which Pran Nath has worked during his distinguished career, from supergravity and string theory to CP violation and dark matter in the universe. Important topics discussed in the Fest include review of precision neutrino results, possible new physics from the muon g-2 results from Brookhaven, evidence for neutrinoless double beta decay, collider searches for supersymmetry, string theory and unification, gravitational mediation of SUSY breaking in superstring theory, extra-galactic sources of high energy neutrinos, and phenomenology using lattice QCD.

These lectures give an elementary introduction to the important recent developments of the applications of N=1 supergravity to the construction of unified models of elementary particle interactions. Topics covered include couplings of supergravity with matter, spontaneous symmetry breaking and the super-higgs effect, construction of supergravity unified models, and the phenomenon of SU(2) x U(1) electroweak-symmetry breaking by supergravity. Experimental consequences of N-1 supergravity unified theory, in particular, the possible supersymmetric decays of the W± and Z0 bosons, are also discussed. The treatment presented encompasses a broad class of models, both of the tree breaking as well as the radiative breaking of SU(2) x U(1). Rules of tensor calculus and the explicit construction of the Lagrangian of the Supergravity-matter couplings are given in the appendix.

The Proceedings of the Workshop covers a broad range of subjects from low energy supersymmetry through supersymmetric grand unification to supergravity and superstring theories. Although the focus was mainly on theoretical problems and ideas, the present and future experimental searches of new particles were also discussed.

The recent high precision results from the LEP supercollider at CERN appear favorable for supergravity unification of the electroweak and the strong forces. The proceedings of the SUSY 93 Workshop focus on further precise predictions of unification which may be observed in the laboratory. In addition, the proceedings cover a wide range of other topics in supersymmetry, supergravity, particle physics, string theory and cosmology and their interconnections. They include both theoretical and experimental papers, hence presenting a complete and comprehensive picture of this important subject.
