    "abstract": "In this paper we extend Hardy\u0027s nonlocality proof for two spin-1/2 particles\n[PRL 71 (1993) 1665] to the case of n spin-1/2 particles configured in the\ngeneralized GHZ state. We show that, for all n \\geq 3, any entangled GHZ state\nviolates the Bell inequality associated with the Hardy experiment. This feature\nis important since it has been shown [PRL 88 (2002) 210402] that, for all n\nodd, there are entangled GHZ states that do not violate any standard n-particle\ncorrelation Bell inequality.",
