With no direct signs of physics beyond the Standard Model (SM),
Effective Field Theories (EFTs) have become the frontier of new
physics exploration. As the Large Hadron Collider (LHC) enters its
High Luminosity era, precision measurements will take centre stage in
unravelling hidden signals.
This talk will focus on high-energy correlated bosonic processes,
showcasing how certain `blind spots' in new physics interpretations
can be resolved using precision techniques. A critical challenge in
EFT analyses is managing theoretical uncertainties—ranging from
operator truncation errors to next-to-leading-order (NLO) QCD and
electroweak effects. I will highlight the essential role of
renormalisation group evolution (RGE) in refining SMEFT predictions.
Crucially, I will demonstrate why NLO electroweak corrections in
background processes are indispensable for robust SMEFT parameter
constraints. Using W^+W^- production as a case study, I will show how
precision calculations reshape our sensitivity to new physics. As the
LHC pushes the boundaries of energy and luminosity, mastering these
uncertainties will be key to unlocking the next frontier of particle
physics.
