We show how a resonance from the recently proposed Lee-Wick StandardModel could lead to the observation at the LHC of a here-proposed new observable called wrong vertex displacement. We study which could be the possible ‘longest-lived’ Lee-Wick particle that could be created at LHC, and we study its possible decays and detections. We conclude through a Monte Carlo simulation that this unique signature for acausal resonances, when analyzed within the Lee-Wick Standard Model, would be measurable in the LHC era if Minimal Flavour Violation is accomplished and if the Lee-Wick electrons mass scale is below  450 GeV.
