Comments on multibrane solutions in cubic superstring field theory

Abstract

In a previous paper, we have studied multi-brane solutions in the context of cubic superstring field theory. The kinetic term of the action was computed for these multi-brane solutions, and for the evaluation of the energy, the equation of motion contracted with the solutions itself was simply assumed to be satisfied. In this paper, we compute the cubic term of the action and discuss the validity of the previous assumption. Additionally, we evaluate the Ellwood's gauge invariant observable.
