The violation of the Lam-Tung relation in the Drell-Yan process serves as a sensitive observable for probing dipole operators as well as three scalar and tensor types of four-fermion operators. Since these operators do not interfere with the SM, their leading contributions to the violation arise at order $1/\Lambda^{-4}$. In this talk, we explore different strategies for constraining these...

Using the framework of the Higgs Effective Field Theory (HEFT), I will discuss multi-Higgs production via gluon-gluon fusion (ggF) and weak boson fusion (WBF). For ggF-induced multi-Higgs production, I will highlight the impact of one-loop HEFT modifications on the Higgs self-couplings and study their effects on the production rates. By including these one-loop radiative corrections and going...

Neutral triple gauge couplings (NTGCs) provide important tests of the gauge sector of the SM and are searched for at the LHC via the process $pp \rightarrow ZZ \rightarrow 4l$ with two on-shell Z bosons.

In the SMEFT, NTGCs are produced at dimension-8 and at 1-loop order, making them doubly suppressed.
A promising alternative interpretation to NTGC searches are SM extensions with vector-like... -

The leading direct and indirect observable effects of arbitrary extra particles of spin 1 are conveniently described by a general effective theory with Proca vector bosons that belong to certain representations of the Standard Model gauge group. Assuming a good high-energy behaviour, we further restrict the possible representations of the extra vectors and derive constraints on their couplings...
