    1414The model describe a U(1) extension of the SM, related to the B-L (baryon minus lepton) charge. 3 RH neutrinos are required to cancel the anomalies, thus providing neutrino masses via the type-I see-saw. A Z' boson is also present, together with a further scalar for the spontaneous symmetry breaking of the further U(1) factor, at TeV scale.

    16 This is the "pure" version of the model, where the mixing between Z and Z' is set to zero.
     16This model describes a 1-dimensional class of Z' models, where a continuous parameter scans over the possible discrete models. The model is fully implemented in the Feynman gauge (also Goldstones and Ghosts).

     18Popular benchmark models from the literature are recovered by setting appropriated relations among the new gauge parameters.

     20 - Pure B-L model: gt = 0. This is the "pure" version of the model, where the mixing between Z and Z' is set to zero. Separate model files for this benchmark model exists.
     21 - SO(10)-inspired U(1)_chi: gt = - 4/5 g1p.
     22 - U(1)_R: gt = -2 g1p.
