On deriving the self-dual antisymmetric tensor field model
Igor Samsonov
(Tomsk, Russia)
Abstract:
We review the derivation of a 6d gauge theory related to
the M5 brane from the Bagger-Lambert-Gustavsson (BLG) model
with the volume preserving diffeomorphisms gauge
group. In particular, the Lagrangian for the 6d self-dual
antisymmetric tensor field appears upon converting three of eight
scalars in the BLG theory into the components of antisymmetric
tensor field in D=6. We develop also a Lorentz-covariant
Lagrangian formulation for such an antisymmetric tensor field in
the free case. This formulation admits a natural
supersymmetrization as well as coupling to 6d gravity.
