Shows that early LHC evidence for a Higgs boson at 142-147 GeV points to PeV-scale split supersymmetry, with moderate-lifetime gluinos (25 microns to 10 years decay length) and an almost purely bino LSP at 70 GeV as discovery signatures.

Shows that long-lived gluinos in split supersymmetry form R-hadrons that stop in detector material, with 10^6 stopping per year in LHC detectors for a 300 GeV gluino. The subsequent delayed decays produce distinctive calorimeter deposits with no tracker or muon chamber activity.

Derives an upper limit on scalar superpartner masses in split supersymmetry from big bang nucleosynthesis constraints on long-lived gluinos. A TeV-mass gluino must decay within 100 seconds, setting the SUSY breaking scale below 10^9 GeV.

Computes one-loop predictions for split supersymmetry, finding the Higgs mass in the range 130-170 GeV for scalar masses above 10^6 GeV, and showing that 1% measurements of gaugino couplings could determine the SUSY breaking scale to within an order of magnitude.
