Researchers constructed new maximally supersymmetric gauged supergravity models in three dimensions. These findings suggest novel supergravity theories beyond eleven dimensions, featuring unique scalar-vector duality generalizations.

Area of Science:

  • Theoretical Physics
  • High-Energy Physics
  • String Theory

Background:

  • Supersymmetric gauged supergravity theories are crucial for understanding fundamental forces.
  • Existing models are often derived from higher-dimensional theories.
  • Three-dimensional supergravity offers a unique theoretical playground.

Purpose of the Study:

  • To construct maximally supersymmetric gauged N = 16 supergravity in three dimensions.
  • To explore a new class of anti-de Sitter supergravities.
  • To investigate potential extensions of supergravity beyond eleven dimensions.

Main Methods:

  • Construction of new theoretical models of supergravity.
  • Analysis of gauge groups and their properties.
  • Exploration of field duality in three dimensions.

Main Results:

  • Successfully constructed maximally supersymmetric gauged N = 16 supergravity in three dimensions.
  • Identified a new class of anti-de Sitter supergravities.
  • Observed a non-Abelian generalization of scalar-vector duality.
  • Highlighted SO(8) x SO(8) as a maximal compact gauge group, with exotic possibilities like F(4(-20)) x G2.

Conclusions:

  • The constructed models are not derivable from known higher-dimensional theories.
  • These findings suggest the existence of supergravity theories beyond eleven dimensions.
  • The non-Abelian duality is a significant feature of these new models.
