Existing LHC dilepton and four-lepton searches, reinterpreted for the minimal U(1)_{B-L} model, exclude gauge couplings down to about 5x10^-6 for a 0.25 GeV Z-prime at maximal Higgs mixing.

abstract
We report a measurement of the parity-violating asymmetry in fixed target electron-electron (Moller) scattering: A_PV = -175 +/- 30 (stat.) +/- 20 (syst.) parts per billion. This first direct observation of parity nonconservation in Moller scattering leads to a measurement of the electron's weak charge at low energy Q^e_W = -0.053 +/- 0.011. This is consistent with the Standard Model expectation at the current level of precision: sin^2\theta_W(M_Z)_MSbar = 0.2293 +/- 0.0024 (stat.) +/- 0.0016 (syst.) +/- 0.0006 (theory).

Searching for a light $Z'$ through Higgs production at the LHC
Existing LHC dilepton and four-lepton searches, reinterpreted for the minimal U(1)_{B-L} model, exclude gauge couplings down to about 5x10^-6 for a 0.25 GeV Z-prime at maximal Higgs mixing.
