In this talk I discuss what I believe are the most interesting recent developments in physics beyond the Standard Model. After some initial comments on neutrino masses, I discuss the status of low-energy supersymmetry and finally turn to describing some recent work in theories with extra spatial dimensions. 1 Neutrinos The most concrete indication for the existence of physics beyond the Standar...

Based on the Weinberg lagrangian or, in a new language, the lagrangian of hidden local symmetry added with the term induced by the anomalous lagrangian of Wess and Zumino, the dynamics of the decays ρ → 4π and ω → 5π is considered. The excitation curves of ρ resonance in its decay to 4π are obtained for the first time. The comparison with recent CMD-2 data is given.

The I = 0; 1; 2; 3 mass splittings of the spin-1=2 octet and spin-3=2 decuplet baryons are analyzed in the 1=Nc expansion combined with perturbative avor breaking. We show there is considerable experimental evidence that the baryon masses satisfy the hierarchy predicted by this expansion. Since avor symmetry-breaking suppression factors alone are not su cient to describe the observed hierarchy,...

This paper gives an overview of the ways that SAS is addressing performance through scalability in SAS Version 9. Scalability features have been implemented in many areas of SAS Version 9 to allow your applications to scale up and scale out. These include: • Multi-Process (MP) CONNECT, • the Scalable Performance Data Engine (SPDE engine), • certain SAS/ACCESS engines, • several scalable SAS pro...

In this paper we present the classification of symmetric designs with parameters (79, 27, 9) on which a nonabelian group of order 39 acts faithfully. In particular, we show that such a group acts semi-standardly with 7 orbits. Using the method of tactical decompositions, we are able to construct exactly 1463 non-isomorphic designs. The orders of the full automorphism groups of these designs all...

The interaction between transport and reconnection processes in magnetically confined plasmas is discussed. There are two complementary processes that we describe. In the first, we consider magnetic islands in a slab geometry to explore the impact of the magnetic island on ion temperature gradient stability. A local theory demonstrates a strong stabilising influence as a consequence of the supp...
