Lower Mass Bound on the Mass via Neutrinoless Double Beta Decay in a 3-3-1 Model

Figure 5

Lower mass bound on the mass from the nonobservation of the neutrinoless double beta decay with different choices for the of scalar field which controls the parameter in (24). The gray solid area denotes Landau pole upper limit [12, 50] and light red denotes the KamLAND-Zen exclusion [46].
