我们利用Berkovits超弦场论在能级截断方案下的表述构造了一个非BPS D膜上的扭结解。扭结的张力再现了预期BPS D膜张力的95%。我们还发现了一个类似于块的解决方案,这是解释为一个扭结反扭结对,并调查它的一些性质。这些结果可以认为是对Berkovits超弦场论结合修正能级截断方案的成功检验。
We construct a kink solution on a non-BPS D-brane using Berkovits' formulation of superstring field theory in the level truncation scheme. The tension of the kink reproduces 95% of the expected BPS D-brane tension. We also find a lump-like solution which is interpreted as a kink-antikink pair, and investigate some of its properties. These results may be considered as successful tests of Berkovits' superstring field theory combined with the modified level truncation scheme.
