Query: Gauge-equivariant Hilbert bimodules and crossed products by
  endomorphisms   C*-endomorphisms arising from superselection structures with non-trivial
centre define a 'rank' and a 'first Chern class'. Crossed products by such
endomorphisms involve the Cuntz-Pimsner algebra of a vector bundle having the
above-mentioned rank and first Chern class, and can be used to construct a
duality for abstract (nonsymmetric) tensor categories vs. group bundles acting
on (nonsymmetric) Hilbert bimodules. Existence and unicity of the dual object
(i.e., the 'gauge' group bundle) are not ensured: we give a description of this
phenomenon in terms of a certain moduli space associated with the given
endomorphism. The above-mentioned Hilbert bimodules are noncommutative
analogues of gauge-equivariant vector bundles in the sense of Nistor-Troitsky.
