چکیده
We provide world sheet non-supersymmetrical actions that describe the coupling of a bosonic string to the tachyon and massless states of both the type-B and type-O theories. The type-B theory is derived as a truncation and chiral doubling of the Ramond-Ramond sector in our previous model that connected the (1,0) heterotic string to a 10D, type-IIB supergravity background. The type-O theory then follows from a " fermionization " of the type-B theory.

Heterotic String Dynamics in the Solvable Lie Algebra Gauge
A revision of the torodial Kaluza-Klein compactification of the massless sector of the E8 × E8 heterotic string is given. Under the solvable Lie algebra gauge the dynamics of the O(p, q)/(O(p)×O(q)) symmetric space sigma model which is coupled to a dilaton, N abelian gauge fields and the Chern-Simons type field strength is studied in a general formalism. The results are used to derive the boson...

We study the Casimir effect for a Bosonic string extended between D-branes, and living in a flat space with an antisymmetric background B-field. We find the Casimir energy as a function of the B-field, and the mass-parameter of the string, and accordingly we obtain a B-dependence correction term to the ground-state mass of the string. We show that for sufficiently large B-field, the ground stat...
متن کاملQuantum Dissipative Systems. Ii. String in a Curved Affine--metric Spacetime
A closed bosonic string in a curved affine--metric spacetime is considered as an example of dissipative quantum field theory. The eonformal anomaly of the trace of the energy--momentum tensor for the string on the affine--metrie manifold is investigated. The two-loop metric beta function for the two-dimensional nonlinear dissipative sigma model is calculated. Examples of nonflat manifolds that ...
متن کاملBosonic String in Affine - Metric Curved Space
The sigma model approach to the closed bosonic string on the affine-metric manifold is considered. The two-loop metric counterterms for the nonlinear twodimensional sigma model with affine-metric target manifold are calculated. The correlation of the metric and affine connection is considered as the result of the conformal invariance condition for the nonlinear sigma model. The examples of the ...
متن کاملStrings as Multi-Particle States of Quantum Sigma-Models
We study the quantum Bethe ansatz equations in the O(2n) sigma-model for physical particles on a circle, with the interaction given by the Zamolodchikovs’ S-matrix, in view of its application to quantization of the string on the S 2n−1 × Rt space. For a finite number of particles, the system looks like an inhomogeneous integrable O(2n) spin chain. Similarly to OSp (2m + n|2m) conformal sigma-mo...
