چکیده

Starting from string field theory for 2d gravity coupled to c=1 matter we analyze the off-shell tree amplitudes of discrete states. The amplitudes exhibit the pole structure and we use the off-shell calculus to extract the residues and prove that just the residues are constrained by the Ward Identities. The residues generate a simple effective action.

The standard model for the electroweak interactions is known 1,2,3,4 to contain vortex solutions that are the usual Nielsen-Olesen U(1) vortices 5 embedded in the larger electroweak symmetry group SU(2) × U(1). After briefly describing these vortex solutions, I will discuss their stability and argue that the presence of bound states can stabilize them. Then I will draw an intimate connection be...

A D > 2 topological string is presented by coupling the 2d topological gravity with the twisted version of the N = 2 superconformal matter with c = 3k/(k − 2). The latter is shown to admit k + 1 chiral primary fields from the SL(2, R)k/U(1) unitary irreducible representations. The analysis of topological contact interactions along with the consistency requirement lead to recursion relations of ...

Scattering amplitudes for discrete states in 2D string theory are considered. Pole divergences of tree-level amplitudes are extracted and residues are interpreted as renormalized amplitudes for discrete states. An effective Lagrangian generating renormalized amplitudes for open string is written and corresponding Ward identities are presented. A relation of this Lagrangian with homotopy Lie alg...

We found an infinite number of potentials surrounding 2d black hole. According to the transmission T and reflection R coefficients for scattering of string fields off 2d black hole, we can classify an infinite number of potentials into three : graviton-dilaton, tachyon and the other types. We suggest that the discrete states from all the Virasoro levels be candidates for new potentials (modes).

We show that there is (p − 1)(p − 1) dimensional semi-relative BRST cohomology at each non-positive ghost number in the (p, p) minimal conformal field theory coupled to two dimensional quantum gravity. These closed string states are related to currents and symmetry charges of ‘exotic’ ghost number. We investigate the symmetry structure generated by the most conventional currents (those of vanis...
