The phenomenology associated with gauge-mediated supersymmetry breaking is presented. A renormalization group analysis of the minimal model is performed in which the constraints of radiativeâ€¦ (More)

The signatures for low energy supersymmetry breaking at the Tevatron are investigated. It is natural that the lightest standard model superpartner is an electroweak neutralino, which decays to anâ€¦ (More)

Chrysomya megacephala (F.), an Old World calliphorid of considerable public health importance, was first discovered in Brazil in 1977 and is now widely distributed in Latin America. Reports that thisâ€¦ (More)

Although supersymmetry has not been seen directly by experiment, there are powerful physics reasons to suspect that it should be an ingredient of nature and that superpartner masses should beâ€¦ (More)

Sensitivity to the square of the cutoff scale of quantum corrections of the Higgs boson mass self-energy has led many authors to conclude that the Higgs theory suffers from a naturalness orâ€¦ (More)

If the reported excess (over the standard model prediction) for Z â†’ bbÌ„ from LEP persists, and is explained by supersymmetric particles in loops, then we show that (1) a superpartner (chargino and/orâ€¦ (More)

Little experimental data bears on the question of whether there is a spontaneously broken hidden sector that has no Standard Model quantum numbers. Here we discuss the prospects of finding evidenceâ€¦ (More)

From a theoretical point of view it is not hard to imagine gaugino masses being much lighter than scalar masses. The dominant contributions to gaugino masses are then their anomaly-mediated values.â€¦ (More)

We consider the SU(2)L Ã— SU(2)R Standard Model brane embedding in an orientifold of T /Z2Ã—Z2. Within defined limits, we construct all such Standard Model brane embeddings and determine the relativeâ€¦ (More)

We compute gluino decay widths in supersymmetric theories with arbitrary flavor and CP violation angles. Our emphasis is on theories with scalar superpartner masses heavier than the gluino such thatâ€¦ (More)
