Open-Closed String Field Theory in the Background B-Field
In this paper, we study open-closed string field theory in the background B-field in the so-called α = p formulation. The string field theory in the infrared gives noncommutative gauge theory in the open string sector. Since this theory includes closed string fields as dynamical variables, we can obtain another string field theory in the same background through the condensation of closed string...
متن کاملWitten ’ s Open String Field Theory in Constant B - Field Background
In this paper we consider Witten’s bosonic open string field theory in the presence of a constant background of the second-rank antisymmetric tensor field Bij. We extend the operator formulation of Gross and Jevicki in this situation and construct the overlap vertices explicitly. As a result we find a noncommutative structure of the Moyal type only in the zero-mode sector, which is consistent w...
متن کاملOn background-independent open-string field theory.
A framework for background independent open-string field theory is proposed. The approach involves using the BV formalism – in a way suggested by recent developments in closed-string field theory – to implicitly define a gauge invariant Lagrangian in a hypothetical “space of all open-string world-sheet theories.” It is built into the formalism that classical solutions of the string field theory...
متن کاملVacuum String Field Theory with B field
We continue the analysis of Vacuum String Field Theory in the presence of a constant B field. In particular we give a proof of the ratio of brane tensions is the expected one. On the wake of the recent literature we introduce wedge–like states and orthogonal projections. Finally we show a few examples of the smoothing out effects of the B field on some of the singularities that appear in VSFT.
متن کاملClosed string exchanges on C/Z2 in a background B-field
In an earlier work it was shown that the IR singularities arising in the nonplanar one loop two point function of a noncommutative N = 2 gauge theory can be reproduced exactly from the massless closed string exchanges. The noncommutative gauge theory is realised on a fractional D3 brane localised at the fixed point of the C /Z2 orbifold. In this paper we identify the contributions from each of ...
