The Tachyon Potential in Witten's Superstring Field Theory

High Energy Physics - Theory 2015-06-25 v2

Abstract

We study the tachyon potential in the NS sector of Witten's cubic superstring field theory. In this theory, the pure tachyon contribution to the potential has no minimum. We find that this remains the case when higher modes up to level two are included.
