Query: Remarks on BMS${}_3$ invariant field theories: correlation functions and
  nonunitary CFTs   We use the isomorphism between the BMS${}_3$ and the $W(2,2)$ algebras to
reconsider some generic aspects of CFTs with the BMS${}_3$ algebra defined as a
chiral symmetry. For unitarity theories, it is known that the extended symmetry
generator acts trivially, and the resulting theory is equivalent to a CFT with
a Virasoro symmetry only. For nonunitary CFTs, we define an operator depending
on a nilpotent variable, and we organize the Verma module through the action of
this new operator. Finally, we find the conditions imposed by the modified Ward
identity.
