			Other bounds come from electroweak precision measurements at the Z pole, the muon's magnetic moment, and limits on flavor changing neutral currents, and reach several hundred GeV. Using universal extra dimensions to explain dark matter yields an upper limit on the compactification scale of several TeV.
