Nowadays it is well established that neutrinos have non-zero masses and mixing angles. Among the different proposals to include them in present models, the seesaw mechanism is the most popular choice.
However, the high seesaw scale makes hard, if not impossible, to test it directly.
On the other hand, supersymmetric models with R-parity violation are a very predictive alternative that can be easily tested at present and future colliders.
In this seminar I will discuss the phenomenology of a model in which R-parity is spontaneously broken at the electroweak scale, generating neutrino masses and giving rise to distinctive signatures, both at the LHC and at low-energy experiments.
