“…[49], as they discussed how the purely cubic SFT could have solutions leading to forms different from the conventional cubic SFT. In particular they noticed that operators built just with ghost oscillators could appear as the kinetic term of an action obtained by shifting by a (formal) solution of the cubic theory.…”

“…In fact, long time ago, Horowitz et.al. [49] constructed a class of formal solutions of the purely cubic string field theory action [50,51] which lead to actions of the above form, with an extra regularity condition Q|I = 0, where |I is the (formal) identity of the star algebra. In particular, these authors noticed that such string field theory would describe no physical excitations around the vacuum in question.…”

Assuming that around the tachyon vacuum the kinetic term of cubic open string field theory is made purely of ghost operators we are led to gauge invariant actions which manifestly implement the absence of open string dynamics around this vacuum. We test this proposal by showing the existence of lump solutions of arbitrary codimension in this string field theory. The key ingredients in this analysis are certain assumptions about the analyticity properties of tachyon Green's functions. With the help of some further assumptions about the properties of these Green's functions, we also calculate the ratios of tensions of lump solutions of different dimensions. The result is in perfect agreement with the known answers for the ratios of tensions of D-branes of different dimensions.

A sliver state is a classical solution of the string field theory of the tachyon vacuum that represents a background with a single D25-brane. We show that the sliver wavefunctional factors into functionals of the left and right halves of the string, and hence can be naturally regarded as a rank-one projector in a space of half-string functionals. By developing an algebraic oscillator approach we are able construct higher rank projectors that describe configurations of multiple D-branes of various dimensionalities and located at arbitrary positions. The results bear remarkable similarities with non-commutative solitons.1

“…This action was the first example of the background independent formulation of the open string field theory [24,18] (see also [25,26,27,28]). It was suggested [1] that it will not likely to be the closed string vacuum which is discussed in the literature [32,33].…”

We study a matrix version of the purely cubic open string field theory as describing the expansion around the closed string vacuum. Any D-branes in the given closed string background can appear as classical solutions by using the identity projectors. Expansion around this solution gives the correct kinetic term for the open strings on the created D-branes while there are some subtleties in the unwanted degree of freedom.
