Scalar Bilepton Dark Matter
read the original abstract
In this work we show that 3-3-1 model with right-handed neutrinos has a natural weakly interacting massive particle (WIMP) dark mater candidate. It is a complex scalar with mass of order of some hundreds of GeV which carries two units of lepton number, a scalar bilepton. This makes it a very peculiar WIMP, very distinct from Supersymmetric or Extra-dimension candidates. Besides, although we have to make some reasonable assumptions concerning the several parameters in the model, no fine tunning is required in order to get the correct dark matter abundance. We also analyze the prospects for WIMP direct detection by considering recent and projected sensitivities for WIMP-nucleon elastic cross section from CDMS and XENON Collaborations.

Large-Field Vacuum Decay in General Multi-Scalar Theories
In the large-field limit, multi-scalar vacuum decay is dominated by a radial (straight-line) bounce, reducing the calculation to minimizing an effective quartic coupling.
