摘要：

An upper limit on the masses of scalar superpartners in split supersymmetry is found by considering cosmological constraints on long-lived gluinos. Over most of parameter space, the most stringent constraint comes from big bang nucleosynthesis. A TeV-mass gluino must have a lifetime of less than 100 seconds to avoid altering the abundances of D and Li-6. This sets an upper limit on the supersymmetry breaking scale m(S) of 10(9) GeV.
