Twisted Chern-Simons supergravity

摘要

We present a noncommutative version ofD = 5Chern-Simons supergravity, where noncommutativity is encoded in a *-product associated to an abelian Drinfeld twist. The theory is invariant under diffeomorphisms, and under the *-gauge supergroup SU(2, 2|4), including Lorentz and N = 4 local supersymmetries.
