A reparametrization invariant nonabelian surface holonomy
Dongsu Bak, Andreas Gustavsson
We introduce a nonabelian surface holonomy that is constructed from a one-form gauge potential that takes values in a loop algebra of the gauge group. The surface holonomy p…
The tensor multiplet in loop space
Dongsu Bak, Andreas Gustavsson
We reformulate the abelian tensor multiplet on a curved spacetime with at least two supercharges in a cohomological form where all the bosonic and fermionic fields become tensor fi…
Lightlike conformal reduction of 6d theories
Andreas Gustavsson
We study 6d superconformal theories. These have a natural lightlike conformal Killing vector, the Dirac current. We perform a conformal dimensional reduction along the Dira…
WZW in the lightlike directions
Andreas Gustavsson
Dimensional reduction of the M5 brane on a Lorentzian manifold along a lightlike direction results in a five-dimensional gauge theory, which can be reformulated covariantly in six…
