We show how a resonance from the recently proposed Lee-Wick Standard Model could lead to theobservation at the LHC of a here-proposed new observable called wrong vertex displacement. Westudy 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 simulationthat this unique signature for acausal resonances, when analyzed within the Lee-Wick StandardModel, would be measurable in the LHC era if Minimal Flavour Violation is accomplished and ifthe Lee-Wick electrons mass scale is below ∼ 450 GeV.
