Duality of string amplitudes in a curved background
We initiate a program to study the relationship between the target space, the spectrum and the scattering amplitudes in string theory. We consider scattering amplitudes following from string theory and quantum field theory on a curved target space, which is taken to be the SU(2) group manifold, with special attention given to the duality between contributions from different channels. We give a ...
متن کاملT-Duality Group for Open String Theory
We study T-duality for open strings on tori Td. The general boundary conditions for the open strings are constructed, and it is shown that T-duality group, which preserves the mass spectrum of closed strings, preserves also the mass spectrum of the open strings. The open strings are transformed to those with different boundary conditions by T-duality. We also discuss the T-duality for D-brane m...
متن کاملT - Duality and the Weakly Coupled Heterotic String
T-duality is a symmetry of the heterotic string to all orders in string perturbation theory. This results in an effective four dimensional supergravity theory with desirable features for phenomenology. T-duality, as well as, generically, an anomalous U(1), is broken by quantum anomalies of the effective field theory. The structure of the full anomaly is presented, and the mechanisms for anomaly...
متن کاملMatrix Strings in Weakly Curved Background Fields
We investigate further the recent proposal for the form of the Matrix theory action in weak background fields. We perform DVV reduction to the multipleD0–brane action in order to find the Matrix string theory action for multiple fundamental strings in curved but weak NS–NS and R–R backgrounds. This matrix sigma model gives a definite prescription on how to deal with R–R fields with an explicit ...
متن کاملGeneralized Duality in Curved String-Backgrounds
The elements of O(d, d,Z) are shown to be discrete symmetries of the space of curved string backgrounds that are independent of d coordinates. The explicit action of the symmetries on the backgrounds is described. Particular attention is paid to the dilaton transformation. Such symmetries identify different cosmological solutions and other (possibly) singular backgrounds; for example, it is sho...
