On Marginal Deformations in Superstring Field Theory
Amer Iqbal, Asad Naqvi
We use level truncated superstring field theory to obtain the effective potential for the Wilson line marginal deformation parameter which corresponds to the constant vacuum expect…
D-Branes And Mirror Symmetry
Kentaro Hori, Amer Iqbal, Cumrun Vafa
We study (2,2) supersymmetric field theories on two-dimensional worldsheet with boundaries. We determine D-branes (boundary conditions and boundary interactions) that preserve half…
Tachyon Condensation on a non-BPS D-brane
Amer Iqbal, Asad Naqvi
We extend the recent computation of the tachyon potential by Berkovits, Sen and Zwiebach by including level two fields and keeping up to level four terms in the action. We find 90.…
Duality and Weyl Symmetry of 7-brane Configurations
Tamas Hauer, Amer Iqbal, Barton Zwiebach
Extending earlier results on the duality symmetries of three-brane probe theories we define the duality subgroup of SL(2,Z) as the symmetry group of the background 7-branes configu…
