  We study the effects of dimension-8 operators on Drell-Yan production of
lepton pairs at the Large Hadron Collider (LHC). We identify a class of
operators that leads to novel angular dependence not accounted for in current
analyses. The observation of such effects would be a smoking-gun signature of
new physics appearing at the dimension-8 level. We propose an extension of the
currently used angular basis and show that these effects should be observable
in future LHC analyses for realistic values of the associated dimension-8
Wilson coefficients.
