In a higher version of how a spin structure induces spinor bundles, so string structure on a manifold transgresses into a kind of spin structure on its free loop space, which is “fusive” with respect to fusion of loops (along trinions). Equipped with this structure this should be a 2-vector bundle on the base space, and this is what is called the stringor bundle.
The idea that String structure on a manifold is a kind of spin structure on its loop space is due to
The idea and the terminology of “stringor bundles” originates with:
An actual construction appears in:
