Tachyon 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 کاملTachyon 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 Superstring Field Theory
It has been conjectured that at the stationary point of the tachyon potential for the Dbrane-anti-D-brane pair or for the non-BPS D-brane of superstring theories, the negative energy density cancels the brane tensions. We study this conjecture using a Wess-ZuminoWitten-like open superstring field theory free of contact term divergences and recently shown to give 60% of the vacuum energy by cond...
متن کاملNon-orientable Boundary Superstring Field Theory with Tachyon Field
We use the BSFT method to study the non-orientable open string field theory (type I). The partition function on the Möbius strip is calculated. We find that, at the one-loop level, the divergence coming from planar graph and unoriented graph cancel each other as expected. 1 Introduction Tachyon condensation is an interesting issue in string theory [1, 2, 3]. To study it, Witten's Boundary Strin...
متن کاملUnorientable Boundary Superstring Field Theory with Tachyon Field
We use the BSFT method to study the unoriented open string theory. The partition function on the Möbius strip is calculated. We find that, at the one-loop level, the divergence coming from planar graph and unoriented graph cancel each other as expected.
