comment Meaning of $\int \phi^\dagger \hat A \psi \:\mathrm dx$
it need not be a "rotation". if by "meaning" you refer to the operator's counterpart in nature, well that will depend on the physical problem you are working on.

comment relevant 4-dimensional theory with interacting vector field
thanks for the comment. do you know if such a term appears in the lagrangian for some physically relevant theory? that's the heart of my question. like you, i can write different terms that would be acceptable but i am interested in a theory which is already of some importance.

Thanks. I will wait for some other answer. If nothing comes up I will move these question to MathOverflow.

comment Equivalent definitions of primary fields in CFT
The first definition is a relation between the new field $g$ evaluated at the new point and the old field $f$ at the the old point. The second definition is a relation between new field at the old point and the old field at the new point. Simply changing the names of the variables in one of the definitions does not give me the other.

comment Equivalent definitions of primary fields in CFT
I don't think that is all b/c then the transformation is $f(\omega) \rightarrow g(\omega) = ...$ which is different from the first definition.
