Geometry of ghost fields
A superconformal vector field can be parametrized by the superfield 
in
the following way:
|
Indeed, it is straightforward to check:
|
We observe that 
is a section of 
, and therefore:
is a section of , and therefore:
|
| ||||||
|
|
Therefore 
lives in 
and 
belongs to 
.
Then we read the types of 
and 
from Eq. (23) taking into account that
lives in and belongs to .
Then we read the types of and
from Eq. (23) taking into account that
the integrable measure should have the type
and 
We get:
Field | is section of |
