The expected profile likelihood ratio exclusion limits for the two-dimensional κ<sub>λ</sub> vs. κ<sub>2V</sub> modifier space, where the solid pink line denotes the 1σ-level exclusion and the dashed orange line denotes the 2σ-level exclusion. The black cross denotes the best-fit values of (κ<sub>λ</sub>,κ<sub>2V</sub>). For both the expected and observed limit plots, the black star indicates the SM prediction (κ<sub>λ</sub>=κ<sub>2V</sub>=1).
