Abstract:
We investigate mechanisms that can trigger supersymmetry breaking in open string vacua. The focus is on backgrounds with D-branes and orientifold planes that have an exact string description, and allow to study some of the quantum effects induced by supersymmetry breaking.
  • string model
  • supersymmetry: symmetry breaking
  • vacuum state
  • dimension: 10
  • string: open
  • scattering amplitude: higher-order
  • membrane model
  • membrane: interaction
  • D-brane
  • orientifold
