Non-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.
متن کاملNormalization of the Boundary Superstring Field Theory Action
The normalization of the boundary superstring field theory action is determined by computing the near on-shell amplitude involving three gauge fields. Contribution to the proceedings of Strings 2001, Mumbai, India. [email protected] formerly Mehta Reasearch Institute of Mathematics & Mathematical Physics. In the recent past there has been some progress in understanding the behaviour of the t...
متن کاملOn The BV Formulation Of Boundary Superstring Field Theory
We propose a Batalin-Vilkovisky (BV) formulation of boundary superstring field theory. The superstring field action is defined in terms of a closed one-form in the space of couplings, and we compute it explicitly for exactly solvable tachyon perturbations. We also argue that the superstring field action defined in this way is the partition function on the disc, in accord with a previous proposal.
متن کاملResolving Witten’s superstring field theory
We regulate Witten’s open superstring field theory by replacing the picturechanging insertion at the midpoint with a contour integral of picture changing insertions over the half-string overlaps of the cubic vertex. The resulting product between string fields is non-associative, but we provide a solution to the A∞ relations defining all higher vertices. The result is an explicit covariant super...
