Multibrane solutions in cubic superstring field theory

Abstract

Using the elements of the so-called $KBc\gamma$ subalgebra, we study a class of analytic solutions depending on a single function $F(K)$ in the modified cubic superstring field theory. We compute the energy associated to these solutions and show that the result can be expressed in terms of a contour integral. For a particular choice of the function $F(K)$, we show that the energy is given by integer multiples of a single D-brane tension.
