A dark matter fermion is shown to simultaneously explain the relic density, satisfy direct detection and collider bounds, and produce observable rates for muon-to-electron transitions in a viable parameter region.

abstract
In this work we show that from the spectrum of particles of a 3-3-1 gauge model with heavy sterile neutrinos we can have up to three Cold Dark Matter candidates as WIMPs. We obtain their relic abundance and analyze their compatibility with recent direct detection experiments, exploring the possibility of explaining the two events reported by CDMS-II. An interesting outcome of this 3-3-1 model, concerning direct detection of two WIMPs in the model, is a strong bound on the symmetry breaking scale, which imposes it to be above 3 TeV.

A singlet scalar leptoquark in the 331LHN model can fully account for the muon anomalous magnetic moment discrepancy with mass above 1.8 TeV (or 6 TeV using 2025 data) while obeying LFV constraints and showing suppressed LHC signals.
In the 331ALP model the second Higgs is predicted above 600 GeV and the Z' above 5.1 TeV, with dark matter mass related to the axion breaking scale under a residual Z2 symmetry.
