Multibrane solutions in cubic superstring field theory

A bstract Using the elements of the so-called KBc γ 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.
