FCNC过程为测试标准模型（SM）和寻找可能的新物理提供了重要的工具。在这项工作中，我们研究了超子衰变的存在。我们发现在SM中，这些罕见的超子衰变的分支比范围为。当包括形状因子的所有误差时，我们发现大多数衰减模式的最终分支分数具有约为的不确定性。在考虑新物理、SM的广义SUSY扩展和最小331模型的贡献后，这些信道的衰减宽度可以增加一个因子。
FCNC processes offer important tools to test the Standard Model (SM), and to search for possible new physics. In this work, we investigate therare hyperon decays in SM and beyond. We find that in SM the branching ratios for these rare hyperon decays range fromto. When all the errors in the form factors are included, we find that the final branching fractions for most decay modes have an uncertainty of aboutto. After taking into account the contribution from new physics, the generalized SUSY extension of SM and the minimal 331 model, the decay widths for these channels can be enhanced by a factor of.
