Query: About the triviality of the higher derivative sector in the abelian
  Lee-Wick model   Canonical quantization is reviewed here for the Abelian Lee-Wick model by
using the Dirac constraints method, a Gupta-Bleuler-like prescription is
implemented and the BRST charge operator for this model is built. New degrees
of freedom associated to the (higher derivatives) Lee-Wick ghost are excluded
from the (physical) space of observables by the imposition of a
Piguet-Nielsen-type BRST-extended symmetry for the Lee-Wick mass term, removing
the Lee-Wick mass parameter of the theory, which implies remove all the
higher-derivative sector. In addition, another prescription based on a new
subsidiary condition of invariance under a purely higher-derivative BRST-type
new symmetry is proposed.
