Anarchic neutrinos from flavor deconstruction: phenomenology of the lepton sector

We investigate the neutrino sector in the framework of flavor deconstruction with an inverse-seesaw realization. This setup naturally links the hierarchical charged-fermion masses to the anarchic pattern of light-neutrino mixing. We determine the viable parameter space consistent with oscillation data and study the phenomenology of heavy neutral leptons (HNL) and lepton-flavor-violating (LFV) processes. Current bounds from direct HNL searches and LFV decays constrain the right-handed neutrino scale to a few TeV, while future $\mu \to e$ experiments will probe most of the region with $\mathrm{\Lambda }\lesssim 10\text{ TeV}$. Among possible realizations, models deconstructing $\mathrm{S}\mathrm{U}(2{)}_{\mathrm{L}}\times \mathrm{U}(1{)}_{\mathrm{B}-\mathrm{L}}$ or $\mathrm{S}\mathrm{U}(2{)}_{\mathrm{L}}\times \mathrm{U}(1{)}_{\mathrm{R}}\times \mathrm{U}(1{)}_{\mathrm{B}-\mathrm{L}}$ are those allowing the lowest deconstruction scale.
