We note that when an electromagnetic tensor is present and an associated Killing-Maxwell system can be constructed in the sense of Carter, the Killing-Maxwell field becomes a PCKY (principal conformal Killing-Yano) tensor or a PGCKY (principal generalized conformal Killing-Yano) tensor, the latter in the presence of torsion. We find some new hidden symmetries of the Chong-Cvetic-Lü-Pope black hole, i.e. we construct two more generalized Stäckel-Killing tensors and the associated generalized Killing-Yano (GKY) tensors. We also explicitly construct a Killing spinor for the specific 5-dimensional minimal gauged supergravity solution that is endowed with a Sasaki structure deformed by torsion mentioned above. https://jhap.du.ac.ir/article_470_aea18eaf7fb286243e5d85a91cced139.pdf
