Tachyon Vacuum in Cubic Superstring Field Theory
In this paper we give an exact analytic solution for tachyon condensation in the modified (picture 0) cubic superstring field theory. We prove the absence of cohomology and, crucially, reproduce the correct value for the D-brane tension. The solution is surprising for two reasons: First, the existence of a tachyon vacuum in this theory has not been definitively established in the level expansio...
متن کاملTachyon Condensation in Cubic Superstring Field Theory
It has been conjectured that at the stationary point of the tachyon potential for the non-BPS D-brane or brane-anti-D-brane pair of superstring theories, the negative energy density cancels the brane tension. We study this conjecture using a cubic superstring field theory with insertion of a double-step inverse picture changing operator. We compute the tachyon potential on levels 1 and 4, obtai...
متن کاملDescent Relations in Cubic Superstring Field Theory
The descent relations between string field theory (SFT) vertices are characteristic relations of the operator formulation of SFT and they provide self-consistency of this theory. The descent relations V 2 |V 1 and V 3 |V 1 in the N S fermionic string field theory in the κ and discrete bases are established. Different regularizations and schemes of calculations are considered and relations betwe...
متن کاملReview of Open Superstring Field Theory
I review the construction of an action for open superstring field theory which does not suffer from the contact term problems of other approaches. This action resembles a Wess-Zumino-Witten action and can be constructed in a manifestly D=4 super-Poincaré covariant manner. This review is based on lectures given at the ICTP LatinAmerican String School in Mexico City and the Komaba 2000 Workshop i...
متن کامل2 00 1 Gauge Invariance and Tachyon Condensation in Cubic Superstring Field Theory
The gauge invariance of cubic open superstring field theory is considered in a framework of level truncation, and applications to the tachyon condensation problem are discussed. As it is known, in the bosonic case the Feynman-Siegel gauge is not universal within the level truncation method. We explore another gauge that is more suitable for calculation of the tachyon potential for fermionic str...
