23 Apr 2005 | | Subject: | hep-ph | | Abstract: | 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 of 10^9 GeV. | | Source: | arXiv, hep-ph/0504210 | | Services: | Forum | Review | PDF | Favorites | |
