标题： Multi-Messenger Theories of Gauge-Mediated Supersymmetry Breaking

摘要： 我们研究包含多个信使的规范介导理论，这些理论具有最一般的SU(5)不变质量与超对称破缺参数。 我们表明这些理论是可预测的，相比最小规范介导模型仅多出两个相关参数。 超荷D项可以显著贡献于右旋带电轻子，使它们的质量更接近左旋轻子。 信使质量必须在SU(5)或一个“信使宇称”下保持不变，以避免电荷守恒的自发破缺。 显示英文摘要

摘要： We study gauge-mediated theories containing several messengers with the most general SU(5)-invariant mass and supersymmetry-breaking parameters. We show that these theories are predictive, containing only two relevant parameters more than the minimal gauge-mediated model. Hypercharge D-terms can contribute significantly to the right-handed charged sleptons and bring them closer in mass to the left-handed sleptons. The messenger masses must be invariant under either SU(5) or a ``messenger parity" to avoid spontaneous breaking of charge conservation.
