Casimir ghosts (introduced by physicists Arnaudon, Bauer,
Frappat and further studied by the mathematician Gorelik) are very
interesting objects which must be used in addition to usual Casimirs in
$Z/2Z$-graded (i. e. supersymmetric) situations. We relate Casimir
Ghosts to invariant integration and Berezinians on symmetric spaces in
supergeometry, and give applications. This is a joint work with Emanuela
Petracci.
