In my latest preprint “Higher contact-like structures and supersymmetry” I provide a novel geometric view of N=1 supersymmety in terms of a polycontact structure on superspace. The preprint can be found at arXiv:1201.4289v1 [math-ph]

The conception of the idea to describe supersymmetry in terms of some contact-like structure came from understanding SUSY mechanics in terms of a contact structure. See my preprint “Contact structures and supersymmetric mechanics” arXiv:1108.5291v2 [math-ph] and an earlier blog entry here.
