abstract

The large and growing library of measurements from the Large Hadron Collider has significant power to constrain extensions of the Standard Model. We consider such constraints on a well-motivated model involving a gauged and spontaneously-broken $B-L$ symmetry, within the Contur framework. The model contains an extra Higgs boson, a gauge boson, and right-handed neutrinos with Majorana masses. This new particle content implies a varied phenomenology highly dependent on the parameters of the model, very well-suited to a general study of this kind. We find that existing LHC measurements significantly constrain the model in interesting regions of parameter space. Other regions remain open, some of which are within reach of future LHC data.

    hep-ph 2026-07 conditional novelty 5.0 of 10

    Current LHC data exclude a significant portion of the Plan B Model's preferred parameter space, and the HL-LHC could extend sensitivity to Z′ masses around 2.5 TeV.
