The would-be Majoron in R-parity-violating supersymmetry

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 the order of the electroweak scale and can be identified as massive sneutrinos.
