  We study the effect of operators generating dipole couplings of the light
quarks to electroweak gauge bosons on several observables at LHC. We start by
demonstrating that the determination of the gauge boson self-couplings from
electroweak diboson production at LHC is robust under the inclusion of those
quark dipole operators even when let them totally unconstrained in the
analysis. Conversely, we determine the bounds that the diboson data imposes on
the light-quark dipole couplings and show that they represent a significant
improvement over the limits arising from Z and W electroweak precision
measurements. We also explore the sensitivity of the Drell-Yan cross section
determination at LHC Run 1, and the results on resonance searches in high
invariant-mass lepton pair production at Run 2 to further constrain the
electroweak dipole couplings of the light quarks.
