29. SMEFT Global Analyses at the Energy Frontier: LHC and Beyond

Global analyses in the SMEFT framework provide a powerful tool to explore new physics. Combining diverse observables is essential to resolve degeneracies among Wilson coefficients, especially since measurements occur at different energy scales, accounting properly for renormalisation group evolution (RGE) is crucial. In this talk, I examine the impact of RGE on a global analysis under flavour...

40. The Higgs trilinear self-coupling at HL-LHC and FCC-ee from a global SMEFT point of view.

Alejo Nahuel Rossia (University of Padua and INFN Sezione di Padova)

Motivated by the updates of the ATLAS and CMS projections of Higgs pair production at the HL-LHC and the release of the Feasibility Study of the FCC-ee, we revisit the sensitivity of the global SMEFT analysis to deformations of the Higgs trilinear self-coupling $\lambda_3$.
We critically reassess the additional information that would be provided by the FCC-ee through NLO corrections to $Zh$...

27. The equivalent Electric Dipole Moment in SMEFT

Nicola Valori - (University of Valencia & IFIC)

The Electric Dipole Moment of the electron (eEDM) is typically investigated in experiments using paramagnetic molecules. However, the physical observable in these searches consists in a linear combination of CP-violating interactions, rather than the eEDM alone, which is commonly referred to as the equivalent EDM of the system. Assuming the presence of new CP-odd physics from heavy degrees of...
