Abstract
We point out that there is a parameter region in supersymmetry with heavy scalars and higgsinos, in which the heavier of bino and wino becomes long-lived as a consequence of the heavy higgsinos. In this region these electroweak gaugino sectors are secluded from each other with very small mixings that are inversely proportional to the higgsino mass, μ. We revisit the bino and bino decays and provide simple formulae for the partial decay rates and the lifetimes in the limit of heavy higgsinos. The scale of μ required for the long-lived electroweak gauginos highly depends on the mass hierarchy between bino and wino. The neutral wino can be long-lived (cτ ≳ 1cm) even with |μ| ≳ 10 TeV if \( {m}_{\tilde{W}}-{m}_{\tilde{B}}\sim 20 \) GeV. We discuss the collider signatures of the long-lived binos and winos in this scenario.
