Definition: Charge convention

For a ghost-number-zero scalar functional $F[\varphi ]$, and a compact vector field $\xi$, define its scalar variation charge by

where ${F_t}^{\xi }$ is the flow of $\xi$.

The term charged means that this derivative is nonzero on some declared data. It does not mean an electric charge, a conserved Noether charge, or a nonzero ghost number.
