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…
Focus Points and Naturalness in Supersymmetry
Jonathan L. Feng, Konstantin T. Matchev, Takeo Moroi
We analyze focus points in supersymmetric theories, where a parameter's renormalization group trajectories meet for a family of ultraviolet boundary conditions. We show that in a c…
Higgs and Z-boson Signatures of Supersymmetry
Konstantin T. Matchev, Scott Thomas
In supersymmetric theories of nature the Higgsino fermionic superpartner of the Higgs boson can arise as the lightest standard model superpartner depending on the couplings between…
New Higgs Signals from Flavor Physics in Large Extra Dimensions
Hsin-Chia Cheng, Konstantin T. Matchev
In a realistic theory with large extra dimensions and TeV scale gravity, there are often other particles living in the extra dimensions in addition to gravitons. A well motivated c…
Multi-TeV Scalars are Natural in Minimal Supergravity
Jonathan L. Feng, Konstantin T. Matchev, Takeo Moroi
For a top quark mass fixed to its measured value, we find natural regions of minimal supergravity parameter space where all squarks, sleptons, and heavy Higgs scalars have masses f…
New backgrounds in Trilepton, Dilepton and Dilepton plus Tau Jet SUSY Signals at the Tevatron
Konstantin T. Matchev, Damien M. Pierce
We determine the Tevatron's reach in supersymmetric parameter space in trilepton, like-sign dilepton, and dilepton plus tau-jet channels, taking all relevant backgrounds into accou…
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…
