开弦场论中a规范解规范不变量的数值计算

Numerical Evaluation of Gauge Invariants for a-gauge Solutions in Open String Field Theory

Isao Kishimoto, Tomohiko Takahashi

摘要:

我们评估规范不变量,行动和规范不变的重叠,数值解满足“a-规范”的条件下,在立方开玻色弦场论的$a$的各种值。我们使用水平截断近似和迭代程序来构造扭曲偶泛空间中的数值解。所得规范不变量是数值稳定的,几乎等于快子凝聚的Schnabl解。我们的结果进一步证明了这些数值解和解析解是规范等价的。

英文摘要:

We evaluate gauge invariants, action and gauge invariant overlap, for numerical solutions which satisfy the "a-gauge" condition with various values of $a$ in cubic open bosonic string field theory. We use the level truncation approximation and an iterative procedure to construct numerical solutions in the twist even universal space. The resulting gauge invariants are numerically stable and almost equal to those of Schnabl's solution for tachyon condensation. Our result provides further evidence that these numerical and analytical solutions are gauge equivalent.
