The standard interpretation is that the light massive neutrinos that we observed oscillating in terrestrial experiments mediate double beta decay. In the minimal 3-3-1 model (3-3-1M), object of our study, there is an additional contribution that stems from the mixing between a new charged vector boson, W, and the Standard Model W boson. Even after setting this mixing to be very small, we show that tight constraints arise from the nonobservation of 0νββ. Indeed, we derive bounds on the mass of the W gauge boson that might exceed those from collider probes and most importantly push the scale of symmetry breaking beyond its validity, leading to an exclusion bound for the minimal 3-3-1 model.
