在超对称理论中，我们计算了具有任意味道和CP破坏角的胶子衰变宽度。我们的重点是理论与标量超伙伴的质量比胶子重，使树级两体衰变是不允许的，这是相关的，例如，在分裂超对称。我们计算了几个具体例子中的胶子衰变分支分数，并表明在大型强子对撞机上唯一可获得的超对称信号可能是四个顶夸克加上丢失的能量，这是合理的。我们展示了另一个例子，其中超对称性的唯一可获得的信号是两个胶子喷流加上丢失的能量。
We compute gluino decay widths in supersymmetric theories with arbitrary flavor and CP violation angles. Our emphasis is on theories with scalar superpartner masses heavier than the gluino such that tree-level two-body decays are not allowed, which is relevant, for example, in split supersymmetry. We compute gluino decay branching fractions in several specific examples and show that it is plausible that the only accessible signal of supersymmetry at the LHC could be four top quarks plus missing energy. We show another example where the only accessible signal for supersymmetry is two gluon jets plus missing energy.
