The 5.2$\sigma$ discrepancy between the 2020 theoretical evaluation of the muon anomalous magnetic moment $a_\mu$ and the most recent measurement made by the Fermilab muon $g-2$ collaboration has the potential to be one of the most significant results in modern particle physics. However, tensions between experimental inputs to the dispersive calculation of the hadronic vacuum polarisation...
The growing array of precision measurements below the electroweak scale holds substantial significance for models of heavy new physics. To fully utilise these measurements, we must understand the running of the many operators of the Low Energy Effective Field Theory (LEFT aka WET). In this talk, I will introduce the LEFT and outline how decomposing operators according to their flavour and...
The discovery potential of the Standard Model Effective Field Theory (SMEFT) is expanded by studying dimension-8 operators and their impact on $W^+W^−$ production in gluon-gluon fusion at the Large Hadron Collider (LHC). This channel, which may contain large Beyond the Standard Model (BSM) contributions in the high-energy tail of its di-lepton mass distribution, presents unique challenges due...
