The Tachyon Potential in the Sliver Frame

Understand

We evaluate the tachyon potential in the Schnabl gauge through off-shell computations in the sliver frame.

• As an application of the results of our computations, we provide a strong evidence that Schnabl's analytic solution for tachyon condensation in open string field theory represents a saddle point configuration of the full tachyon potential.
• Additionally we verify that Schnabl's analytic solution lies on the minimum of the effective tachyon potential.
