Supersymmetry at the LHC and The Theory of R-parity

Understand

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.
