Real Tachyon Vacuum Solution without Square Roots

High Energy Physics - Theory 2017-04-11 v1

Abstract

In this note we present a real tachyon vacuum solution for open bosonic string field theory which does not require computing square roots of states in the wedge algebra. We study its algebraic structure, prove the equation of motion and show that the solution supports no cohomology. Finally we show that its energy is in agreement with the value predicted by Sen's conjecture.
