Abstract
A linear increase with the volume of the topological susceptibility can signal spontaneous breaking of parity P and time inversion T , due to a nonzero vacuum expectation value of the topological charge Q . Such a breaking would produce a nonzero electric dipole moment of the neutron, d n . An upper limit to d n is derived from numerical simulations at increasing volumes.
