Ward Identities in Two - Dimensional String Theory
I study the Ward identities of the w∞ symmetry of the two-dimensional string theory. It is found that, not just an isolated vertex operator, but also a number of vertex operators colliding at a point can produce local charge non-conservation. The structure of all such contact terms is determined. As an application, I calculate all the non-vanishing bulk tachyon amplitudes directly through the W...
متن کاملCorrelation Functions from Two-dimensional String Ward Identities
We rederive the w∞ Ward identities, starting from the existence of trivial linearized gauge invariances, and using the method of canceled propagators in the operator formalism. Recursion relations for certain classes of correlation functions are derived, and these correlation function are calculated exactly. We clarify the relation of these results with another derivation of the Ward identities...
متن کاملFlux-vacua in Two Dimensional String Theory
We analyze the two dimensional type 0 theory with background RR-fluxes. Both the 0A and the 0B theory have two distinct fluxes q and q̃. We study these two theories at finite temperature (compactified on a Euclidean circle of radius R) as a function of the fluxes, the tachyon condensate μ and the radius R. Surprisingly, the dependence on q, q̃ and μ is rather simple. The partition function is the...
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 Massive Scattering Amplitudes and Ward Identities in String Theory
We calculate bosonic open string one-loop massive scattering amplitudes for some lowlying string states. By using the periodicity relations of Jacobi theta functions, we explicitly prove an infinite number of one-loop type I stringy Ward identities derived from type I zeronorm states in the old covariant first quantized (OCFQ) spectrum of open bosonic string. The subtlety in the proofs of one-l...
