One-loop threshold corrections in the minimal U(1)_{L_mu-L_tau} seesaw model break the tree-level two-zero minor structure, relaxing the lower bound on total neutrino mass and easing cosmological tension.

abstract
We consider the gauging of $L_\mu - L_\tau$ as an explanation of a possibly large muon anomalous magnetic moment. We then show how neutrino masses with bimaximal mixing may be obtained in this framework. We study the novel phenomenology of the associated gauge boson in the context of present and future high-energy collider experiments.

Treating longitudinal and transverse polarizations of light Z' bosons independently modifies the SN1987A bounds on their parameter space in the Lμ-Lτ model.
For Lμ-Lτ gauge forces with g ≳ 10^{-18}, Schwinger neutrino production in neutron stars alters composition, invalidates merger constraints at g ≳ 10^{-17}, and could yield detectable ~100 MeV neutrino fluxes from young stars at ~100 pc.
Re-evaluation of sub-GeV Lμ-Lτ gauge boson constraints from beam-dump production modes and multiple supernova observables, highlighting differences from existing literature.
Future muon colliders can probe Kaluza-Klein excitations of a 5D U(1)_{Lμ-Lτ} gauge boson across MeV to TeV masses with couplings down to 10^{-5}.
In a U(1) gauged seesaw model, Z'Z' fusion processes at muon colliders enable HNL pair production via Z'Z'→H→NN and Z'Z'→NN, yielding LNV signals not suppressed by Higgs mixing.
Five-dimensional U(1)_{Lμ-Lτ} model predicts multiple gauge bosons whose contributions to elastic neutrino-electron scattering can be probed at DUNE, covering much of the muon (g-2) consistent parameter space.
