We extend the known Universal One-Loop Effective Action (UOLEA) by all operators which involve scalars and fermions, not including contributions arising from open covariant derivatives. Our generic analytic expressions for the one-loop Wilson coefficients of effective operators up to dimension six allow for an application of the UOLEA to a broader class of UV-complete models. We apply our generic results to various effective theories of supersymmetric models, where different supersymmetric particles are integrated out at a high mass scale.

完成标量和费米子通用一环有效动作

我们通过所有涉及标量和费米子的算子扩展了已知的通用单循环有效作用(UOLEA),不包括来自开放协变导数的贡献。我们的有效算子的单环威尔逊系数的通用分析表达式最多可达 6 维,允许将 UOLEA 应用于更广泛的 UV 完全模型。我们将我们的一般结果应用于超对称模型的各种有效理论,其中不同的超对称粒子以高质量集成。
