Description
Since the discovery of the Higgs boson, no clear footprints of New Physics (NP) have been observed at the LHC. This absence suggests a separation between the NP scale and the electroweak scale. In this scenario, Effective Field Theories (EFTs) provide a model-independent framework to analyze LHC and low-energy data and to search for indirect signs of beyond-the-Standard-Model effects. In particular, Drell–Yan (DY), diboson production (WV), and Higgs production in association with a gauge boson (VH) are sensitive to NP, especially in the high-energy tails of differential kinematic distributions. These energy-enhanced effects enable the extraction of constraints that can be competitive with those from electroweak precision observables, such as those measured at LEP, as well as flavor observables, such as semileptonic meson decays. In this talk, I will discuss how these processes can probe dimension-six Wilson coefficients in the Standard Model Effective Field Theory, highlighting the complementarity between high- and low-energy probes. I will also show how the High-Luminosity LHC can shed light on existing flavor anomalies.
