We use hydrodynamical simulations to investigate the response of geometrically thin, self-gravitating, singular isothermal disks of gas to imposed rigidly rotating spiral potentials. By minimizing reflection-induced feedback from boundaries , and by restricting our attention to models where the swing parameter X ∼ 10, we minimize the swing amplification of global normal modes even in models whe...

Using a high statistics sample of photo-produced charm particles from the FOCUS experiment at Fermilab, we report results of a search for eight rare and StandardModel-forbidden decays: D+, D+ s → h ±μ∓μ+ (with h = π,K). Improvement over previous results by a factor of 1.7–14 is realized. Our branching ratio upper limit D+ → π+μ−μ+ of 8.8× 10−6 at the 90% C.L. is below the current MSSM R-Parity ...

We study chiral SU(N) supersymmetric gauge theories with matter in the antifundamental and antisymmetric representations. For SU(5) with two families, we show how to reproduce the non-perturbatively generated superpotential, and we discuss dynamical supersymmetry breaking purely in terms of the Konishi anomaly. We apply the same technique in general to SU(N) with one family. We also briefly com...
