银系中的快子势

The Tachyon Potential in the Sliver Frame

E. Aldo Arroyo

摘要:

我们通过在银框架下的离壳计算来计算Schnabl规范中的快子势。作为我们的计算结果的应用,我们提供了一个强有力的证据,Schnabl的解析解快子凝聚在开弦场论代表了鞍点配置的完整的快子潜力。此外,我们验证了Schnabl的解析解位于有效快子势的最小值。

英文摘要:

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.
