It would seem to be natural to use
, instead of
, to denote the antifield of
. But in practice such a notation turns out to be absolutely disastrous.
The previously discussed local rescaling symmetries of
are extended to the BV action:
2 Relation to standard notations for antifields
is an auxiliary field, and we will integrate it out.
In other words, the only dynamical component of
is
. When we insert
some operator, we should take care to only insert
via the combination
.
We are left with and
.
In PerturbativeSuperstringTheoryRevisited,

is called

we agree with their Equation (3.20).
