Suppression of interference between the SM and the dimension-six operators is well established and complicate the extraction of constraints from the LHC data. However, it can also be seen as an opportunity to motivate shape measurements. In this presentation, I will show a few examples of resurrection by differential measurements and show how they give more stable constraints when higher order...

We demonstrate diagrammatically the cancellation of chiral anomalies in the Standard Model Effective Field Theory (SM EFT), achieved through by a consistent choice of loop momentum routing in triangle diagrams with dimension-6 operator insertions. By enforcing gauge invariance and Bose symmetry, we show that Goldstone boson contributions cancel anomalies arising from massive gauge boson...

The discovery potential of the Standard Model Effective Field Theory (SMEFT) can be enhanced by including dimension-8 operators and their impact on di-boson production at the Large Hadron Collider (LHC), particularly in the high energy tails of the distributions. Although $W^+W^-$ production has a large leptonic cross section, it is subject to a tight jet-veto to suppress the otherwise...

In the Standard Model (SM), electroweak (EW) corrections become significant at high energies, particularly at the tera-electronvolt scale and beyond, due to the presence of Sudakov logarithms. At these energy scales, the Standard Model Effective Field Theory (SMEFT) framework provides an enhanced sensitivity to potential new physics effects. This motivates the inclusion of EW corrections not...
