We show that high energy measurements of Drell-Yan at the LHC can serve as electroweak precision tests. Dimension-6 operators, from the Standard Model Effective Field Theory, modify the high energy behavior of electroweak gauge boson propagators. Existing measurements of the dilepton invariant mass spectrum, from neutral current Drell-Yan at 8 TeV, have comparable sensitivity to LEP. We propose measuring the transverse mass spectrum of charged current Drell-Yan, which can surpass LEP already with 8 TeV data. The 13 TeV LHC will elevate electroweak tests to a new precision frontier.

  1. Heavy Vector Triplets at a Muon Collider

    hep-ph 2026-05 unverdicted novelty 5.0

    Muon colliders can probe heavy vector triplets up to 12 TeV, competitive with HE-LHC but below FCC-hh projections, including indirect electroweak precision limits.

    hep-ph 2026-05 unverdicted novelty 3.0

    Universal SMEFT fits to pseudo-data from neutral and charged Drell-Yan processes at HL-LHC can detect universal new physics and extract its properties stably across EFT truncation orders.
