N-extended Maxwell supergravities as Chern-Simons theories in three spacetime dimensions
We present a new class of three-dimensional N-extended supergravity theories based on the N-extended Maxwell superalgebra with central charges and so(N) internal symmetry generators. The presence of so(N) generators is required in order to define a non-degenerate invariant inner product. Such symmet...

| Summary: | We present a new class of three-dimensional N-extended supergravity theories based on the N-extended Maxwell superalgebra with central charges and so(N) internal symmetry generators. The presence of so(N) generators is required in order to define a non-degenerate invariant inner product. Such symmetry allows us to construct an alternative supergravity action without cosmological constant term. Interestingly, the new theories can be obtained as a flat limit of a N-extended AdS-Lorentz supergravity theories enlarged with so(N) gauge fields. |
