Stop and Sbottom Searches in Run II of the Fermilab Tevatron
Regina Demina, Joseph D. Lykken, Konstantin T. Matchev +1
We estimate the Tevatron Run II potential for top and bottom squark searches. We find an impressive reach in several of the possible discovery channels. We also study some new chan…
The Shape of Gravity
Joseph Lykken, Lisa Randall
In a nontrivial background geometry with extra dimensions, gravitational effects will depend on the shape of the Kaluza-Klein excitations of the graviton. We investigate a consiste…
Asymmetrical large extra dimensions
Joseph Lykken, Satyanarayan Nandi
We study scenarios in which there is a hierarchy of two sets of large compactified extra dimensions. One particularly interesting case has a single millimeter size extra dimension…
Superstring Theory and CP- Violating Phases: Can They Be Related?
M. Brhlik, L. Everett, G. L. Kane +1
We investigate the possibility of large CP- violating phases in the soft breaking terms derived in superstring models. The bounds on the electric dipole moments (EDM's) of the elec…
A Resolution to the Supersymmetric CP Problem with Large Soft Phases via D-branes
M. Brhlik, L. Everett, G. L. Kane +1
We examine the soft supersymmetry breaking parameters that result from various ways of embedding the Standard Model (SM) on D-branes within the Type I string picture, allowing the…
New and Improved Superstring Phenomenology
Joseph D. Lykken
Recent developments in string theory have important implications for cosmology. Topics discussed here are inflation, the cosmological constant, smoothing of cosmological singularit…
Supersymmetry Signatures with Tau Jets at the Tevatron
Joseph D. Lykken, Konstantin T. Matchev
We study the supersymmetry reach of the Tevatron in channels containing both isolated leptons and identified tau jets. In the most challenging case, where the branching ratios of g…
Status of Muon Collider Research and Development and Future Plans
Charles M. Ankenbrandt
The status of the research on muon colliders is discussed and plans are outlined for future theoretical and experimental studies. Besides continued work on the parameters of a 3-4…
