Abstract:
We discuss the possible signatures at the Large Hadron Collider in models
where R-parity is spontaneously broken. In the context of the minimal gauge
theory for R-parity, we investigate signals with multileptons which can provide
an unique test of this theory. The possible impact of these ideas for the
search of supersymmetry at the Large Hadron Collider is discussed. We also
discuss the constraints coming from cosmology due to the existence of two light
sterile neutrinos in the theory.
