Open strings in a background guage field Laidlaw, Mark

Abstract

The vacuum energy for open strings in a constant gauge field background is calculated for the disk and the annulus in a path integral formalism. This same formalism is then used to reproduce and generalize previous results for D-brane non-commutative geometry at string disk level. The contribution to non-commutative geometry from string annulus diagrams is calculated, and shown to be proportional to the divergence of the open string tachyon.
