The would-be majoron in R-parity-violating supersymmetry
arXiv:hep-ph/0210273 · doi:10.1103/PhysRevD.67.036002
Abstract
In lepton-number-violating supersymmetric models, there is no natural choice of basis to distinguish the down-type Higgs and lepton superfields. We employ basis-independent techniques to identify the massless majoron and associated light scalar in the case of spontaneously-broken lepton number (L). When explicit L-violation is added, these two scalars can acquire masses of order the electroweak scale and can be identified as massive sneutrinos.
