Focus Point Supersymmetry: Proton Decay, Flavor and CP Violation, and the Higgs Boson Mass
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 of this framework for low energy constraints and the
light Higgs boson mass. Undesirable contributions to proton decay and electric
dipole moments, generic in many supersymmetric models, are strongly suppressed.
As a result, the prediction for alpha_s in simple grand unified theories is 3
to 5 standard deviations closer to the experimental value, and the allowed
CP-violating phases are larger by one to two orders of magnitude. In addition,
the very heavy top and bottom squarks of focus point supersymmetry naturally
produce a Higgs boson mass at or above 115 GeV without requiring heavy
gauginos. We conclude with an extended discussion of issues related to the
definition of naturalness and comment on several other prescriptions given in
the literature.Comment: 31 pages, 10 figures, references added, version to appear in Phys.
