在自然界的超对称理论中，希格斯玻色子的希格斯诺费米子超伴子可以作为最轻的标准模型超伴子出现，这取决于希格斯和超对称破缺扇区之间的耦合。本文讨论了Higgsino对产生和衰变到Goldstone费米子的超对称破缺和Higgs玻色子H或规范玻色子Z或{gamma}的过程。相对干净的双玻色子最终状态hh、h{gamma}、hZ、Z{gamma}或ZZ，具有大量丢失的能量结果。后者的渠道提供了新的发现模式的超对称性在高能对撞机，因为事件与Z玻色子通常被拒绝在超对称性搜索。此外，具有真实的希格斯玻色子的最终态可以潜在地提供有效的渠道来发现和研究费米实验室Tevatron运行II的希格斯信号。(c)2000年，美国物理学会。
In supersymmetric theories of nature the Higgsino fermionic superpartner of the Higgs boson can arise as the lightest standard model superpartner depending on the couplings between the Higgs and supersymmetry breaking sectors. In this Brief Report the production and decay of Higgsino pairs to the Goldstone fermion of supersymmetry breaking and the Higgs boson h, or gauge bosons Z or {gamma} are considered. Relatively clean diboson final states hh, h{gamma}, hZ, Z{gamma}, or ZZ with a large amount of missing energy result. The latter channels provide novel discovery modes for supersymmetry at high energy colliders since events with Z bosons are generally rejected in supersymmetry searches. In addition, final states with real Higgs bosons can potentially provide efficient channels to discover and study a Higgs signal at the Fermilab Tevatron run II.
