Noncommutative Tachyon from Background Independent Open String Field Theory
We analyze the tachyon field in the bosonic open string theory in a constant B-field background using the background independent open string field theory. We show that in the large noncommutativity limit the action of tachyon field is given exactly by the potential term which has the same form as in the case without B-field but the product of tachyon field is taken to be the star product.

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 کاملTachyon Condensation and Open String Field theory
We perform canonical quantization of the open string on a unstable D-brane in the background of the tachyon condensation. Evaluating the Polyakov path-integral on a stripe, we obtain the field theoretical propagator in the open string theory. As the condensation occurs the string field theory is continuously deformed. At the infrared fixed point of the condensation, the open string field on the...
متن کاملNormalisation of the Background Independent Open String Field Theory Action
It has been shown recently that the background independent open string field theory provides an exact description of the tachyon condensation on unstable D-branes of bosonic string theory. In this analysis the overall normalisation of the action was chosen so that it reproduces the conjectured relations involving tachyon condensation. In this paper we fix this normalisation by comparing the on-...
متن کاملOpen String Field Theory on Noncommutative Space
We study Witten’s open string field theory in the presence of a constant B field. We construct the string field theory in the operator formalism and find that, compared to the ordinary theory with no B field, the vertices in the resulting theory has an additional factor. The factor makes the zero modes of strings noncommutative. This is in agreement with the results in the first-quantized formu...
