Excited D-brane decay in Cubic String Field Theory and in Bosonic String Theory
M. R. Garousi, G. R. Maktabdaran
In the cubic string field theory, using the gauge invariant operators corresponding to the on-shell closed string vertex operators, we have explicitly evaluated the decay amplitude…
On-shell S-matrix and tachyonic effective actions
Mohammad R. Garousi
We evaluate various disk level four-point functions involving the massless scalar and tachyon vertex operators in the presence of background B-flux in superstring theory. By studyi…
Gravity on Noncommutative D-Branes
F. Ardalan, H. Arfaei, M. R. Garousi +1
The effective action for the low energy scattering of two gravitons with a D-brane in the presence of a constant antisytmetric field in bosonic string theory is calculated and…
Gauge Invariant Operators and Closed String Scattering in Open String Field Theory
Mohsen Alishahiha, Mohammad R. Garousi
Using the recent proposal for the observables in open string field theory, we explicitly compute the coupling of closed string tachyon and massless states with the open string stat…
