We study how nonstandard neutrino interactions (NSI) may be probed by a combination of coherent elastic neutrino-nucleus scattering, neutrino oscillation and collider data, from COHERENT, DUNE, T2HK and the high-luminosity (HL) LHC. We focus on NSI induced by a new flavored gauge boson Z′ in a generic anomaly-free ultraviolet-complete model. For Z′ masses above 10 GeV, the HL-LHC has the best sensitivity regard-less of the flavor structure of the model. For masses between 0.01 GeV− 10 GeV, current LHCb data and future COHERENT data have the best sensitivity unless the Z′ couplings to the first and second generation leptons are suppressed, in which case DUNE and T2HK have the best sensitivity. For Z′ masses between about 5 MeV− 20 MeV, DUNE and T2HK have the best sensitivity. We also show how joint analyses of COHERENT and LHC data may constrain such models.
