26. Understanding the Interplay of PDFs and BSM Effects

Ella Cole (DAMTP, University of Cambridge)

Indirect searches for new physics increasingly rely on precise theoretical predictions in the high-energy tails, with Parton Distribution Functions (PDFs) being one of the main bottlenecks.

In this talk, I explore the interplay between the fits of Standard Model Effective Field Theory (SMEFT) Wilson coefficients and PDFs in two key sectors at the LHC, the Drell-Yan and the top sector. I...

25. Global SMEFT analyses and the role of Higgs measurements

Mauro Valli (INFN Rome)

We present constraints on dimension-6 Standard Model Effective Field Theory (SMEFT) operators from a global fit to electroweak, Drell-Yan, Higgs-boson, top-quark, and flavour observables. The analysis is performed under different flavour symmetry assumptions, including $U(3)^5$ and $U(2)^5$, and considers both global and single-coefficient fits. The scale dependence of the Wilson coefficients...

2. The SMEFT way to New Physics

Simone Tentori (UCLouvain)

SMEFT is a powerful framework to explore imprint of New Physics when the mass of the new states is out of experimental reach. In recent years, significant effort has been devoted to performing global fits in order to correlate deviations observed across different measurements. However, the large dimensionality of the parameter space can limit the sensitivity of this approach and obfuscate the...

67. Global Analysis of Linear Standard Model Extensions

Victor Maura Breick (King's College London)

Linear Standard Model Extensions (LSMEs) are a motivated set of simplified models for exploring the phenomenology of physics beyond the Standard Model (BSM) and assessing the reach of future colliders. They capture a wide range of BSM physics: any particle coupling linearly to the Standard Model (SM) with relevant or marginal interactions is an LSME. Examples include vector-like fermions, new...
