Complex poles in the ghost propagator induce persistent interactions at asymptotic times, rendering negative-norm ghost states indistinguishable from superpositions of positive-norm multi-particle states and eliminating free asymptotic ghost particles.

Massive ghost in quadratic gravity is confined via BRST quartet when bound to FP ghost, with its asymptotic field a massive dipole and the bound state obeying massive Klein-Gordon.
Using superfield formalism, the paper links color confinement in QCD to massive gluons and quarks obeying dipole field equations and conjectures an analogous resolution to the unitarity problem in quadratic gravity via ghost confinement.
