Open string field theory without open strings
Witten’s cubic open string field theory is expanded around the perturbatively stable vacuum, including all scalar fields at levels 0, 2, 4 and 6. The (approximate) BRST cohomology of the theory is computed, giving strong evidence for the absence of physical open string states in this vacuum.
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 کاملKinks of open superstring field theory
We construct approximate kink solutions of supersymmetric open string field theory at lowest level when non-local operators in the tachyon effective action are fully taken into account. To this purpose we derive two duplication formulæ for products of incomplete gamma functions, which determine the level of approximation of the solutions. The time kink is an instanton of the Euclidean theory wi...
متن کاملOpen Strings and 3d Topological Field Theory
In the perturbative formulation of string theory the partition function in the background of D-branes can be expanded as Z string = g,b g −2+2g+b s Z g,b. (1) Here Z g,b is the value of the diagram given by a Riemann surface of genus g with b boundary components. One way to compute the numbers Z g,b is to work in conformal gauge. In this gauge one obtains a conformal field theory (CFT) living o...
متن کاملManifest Electromagnetic Duality in Closed Superstring Field Theory
The free action for massless Ramond-Ramond fields is derived from closed superstring field theory using the techniques of Siegel and Zwiebach. For the uncompactified Type IIB superstring, this gives a manifestly Lorentz-covariant action for a self-dual five-form field strength. Upon compactification to four dimensions, the action depends on a U(1) field strength from 4D N=2 supergravity. Howeve...
