1 Boundary String Field Theory at One - loop
We apply the boundary string field theory (BSFT) to a unstable D-brane system to study the open-closed string duality at one loop in the presence of the tachyon condensation. The partition function at one-loop level is calculated by using both open and closed string channels. We find that the results from two different channels coincide, thus the open-closed string duality holds even off-shell.
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملOne-loop Effective Action in Open-string Theory
This is a summary of the analysis of the one-loop effective action in Z2-orbifold compactifications of type-I theory presented in references [1,2]. We show how, for non-abelian group factors, the threshold effects are ultraviolet finite though given entirely by a six-dimensional field theory expression. We also discuss implications for the equivalence between Type-I and Heterotic four dimension...
متن کاملThe Dilaton Equation in Semirigid String Theory
We show how to obtain explicit integration measures on ordinary moduli space corresponding to the correlation functions of pure 2-dimensional topological gravity. In particular our prescription tells how to remove the zero modes of the βγ system. We then use our formula to derive the “dilaton equation” introduced by E. Verlinde and H. Verlinde,a relation between the N-point and (N − 1)-point co...
متن کاملM-theory and the string genus expansion
The partition function of the membrane is investigated. In particular, the case relevant to perturbative string theory of a membrane with topology S1×Σ is examined. The coupling between the string world sheet Euler character and the dilaton is shown to arise from a careful treatment of the membrane partition function measure. This demonstrates that the M-theory origin of the dilaton coupling to...
