Focus Point Supersymmetry: Proton Decay, Flavor and CP Violation, and the Higgs Boson Mass
Jonathan L. Feng, Konstantin T. Matchev
In focus point supersymmetry, all squarks and sleptons, including those of the third generation, have multi-TeV masses without sacrificing naturalness. We examine the implications…
Light Axion within the Next-to-Minimal Supersymmetric Standard Model
Bogdan A. Dobrescu, Konstantin T. Matchev
We analyze the Higgs sector in the Next-to-Minimal Supersymmetric Standard Model, emphasizing the possibility of a light CP-odd scalar (axion) in the spectrum. We compute the coupl…
Prospects for Indirect Detection of Neutralino Dark Matter
Jonathan L. Feng, Konstantin T. Matchev, Frank Wilczek
Dark matter candidates arising in models of particle physics incorporating weak scale supersymmetry may produce detectable signals through their annihilation into neutrinos, photon…
Higgs Boson Decays to CP-odd Scalars at the Tevatron and Beyond
Bogdan A. Dobrescu, Greg Landsberg, Konstantin T. Matchev
In extended Higgs models, the Higgs boson may decay into a pair of light CP-odd scalars, with distinctive collider signatures. We study the ensuing Higgs signals at the upgraded Te…
Neutralino Dark Matter in Focus Point Supersymmetry
Jonathan L. Feng, Konstantin T. Matchev, Frank Wilczek
In recent work, it has been argued that multi-TeV masses for scalar superpartners are not unnatural. Indeed, they appear to have significant phenomenological virtues. Here we explo…
Discovering a Light Higgs Boson with Light
Greg Landsberg, Konstantin T. Matchev
We evaluate the prospects for detecting a non-standard light Higgs boson with a significant branching ratio to two photons, in Run II of the Fermilab Tevatron. We derive the reach…
