We illustrate the importance of interference revival when higher order corrections are included, by presenting LO and NLO differential cross-sections and K-factors for three processes that are sensitive to the dimension-6 SMEFT operator OW: Z-plus-two-jets (Zjj) production through Vector Boson Fusion (VBF), leptonic diboson WZ and . We show how lifting the interference suppression at LO, through suitable variables and cuts, is necessary to get reliable predictions at NLO. We also show bounds on CW obtained from these observables.

通过干扰恢复在 NLO 校正下 EFT 可观测的稳定性



我们通过展示对 6 维 SMEFT 算子 OW 敏感的三个过程的 LO 和 NLO 差分截面和 K 因子来说明在包含高阶校正时干扰恢复的重要性:通过矢量玻色子融合 (VBF) 产生 Z 加两个射流 (Zjj),轻子双玻色子 WZ 和 Wγ。我们展示了如何通过合适的变量和削减来解除 LO 的干扰抑制,以获得 NLO 的可靠预测。我们还显示了从这些 observable 获得的 CW 边界。
