Arutyunov, G., Pankiewicz, A. and Stefanski, B. (2001). Boundary Superstring Field Theory Annulus Partition Function in the Presence of Tachyons. Journal of High Energy Physics, 2001(JHEP06), 049. doi: 10.1088/1126-6708/2001/06/049

Abstract

We compute the Boundary Superstring Field Theory partition function on the annulus in the presence of independent linear tachyon profiles on the two boundaries. The R-R sector is found to contribute non-trivially to the derivative terms of the space-time effective action. In the process we construct a boundary state description of D-branes in the presence of a linear tachyon. We quantize the open string in a tachyonic background and address the question of open/closed string duality.
