论文摘要
最近，SMEFT以及理论和计算工具的最高级曲目已成为测试拟议BSM方案的可行性的有效平台。以对称性为骨架，较高的质量尺寸（$ \ geq 5 $）SMEFT操作员构成了\ textit {lingua franca}，用于研究和比较紫外线模型对低能观测值的直接或间接影响。当代粒子碰撞实验的可访问能量尺度的稳定增加促使我们检查了超出领先顺序的有效操作员，并研究其可测量的影响以及它们与适当的BSM建议的联系。我们迈出了下一步，通过将以前用于CP，BARYON和LEPTON NUMBER CONERVING DIMENSION-6运算符的图形方法扩展到完整的纯玻璃体SMEFT操作员集合，将SMEFT操作员的可能的UV根划定了可能的紫外线根。我们分类了各种各样的Feynman图表，阐明了操作员在遵守极简主义概念的同时，如何封装了重场传播器。
In recent times, SMEFT, along with a superlative repertoire of theoretical and computational tools, has emerged as an efficacious platform to test the viability of proposed BSM scenarios. With symmetry as the backbone, higher mass dimensional ($\geq 5$) SMEFT operators constitute the \textit{lingua franca} for studying and comparing the direct or indirect effects of UV models on low energy observables. The steady increase in the accessible energy scales for contemporary particle collision experiments prompts us to inspect effective operators beyond the leading order and investigate their measurable impact as well as their connections with the appropriate BSM proposals. We take the next step in delineating the possible UV roots of SMEFT operators by extending our diagrammatic approach, previously employed for CP, baryon, and lepton number conserving dimension-6 operators, to the complete set of purely bosonic SMEFT operators up to mass dimension-8. We catalogue a diverse array of Feynman diagrams elucidating how the operators encapsulate heavy field propagators while abiding by a notion of minimalism.
