Looking for new physics at the LHC is often motivated by scenarios with Z_2 symmetries, which have dark matter candidates, and lead to events with large missing energy. However, These Z_2 symmetries have ample scope of getting broken, as a result of which one can have new physics signals without large missing energy. We discuss various scenarios of this kind, and the all-important question of how to distinguish among them. We emphasize the role of our recently proposed same-sign trilepton signal in this context, not only as a distinctive mark of R-parity violating supersymmetry, but also in uncovering the dynamics underlying R-parity violation.
