Abstract
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.
