本文描述了一种在开玻色弦场论中获得对应于精确边缘形变的解析解的方法。对于光子边缘形变,我们有一个明确的解析解的所有订单。我们的结构是基于一个纯规范的解决方案,规范场是不是在希尔伯特空间。我们证明了解本身是完全正则的。我们研究了它的规范变换并明确计算了一些系数。最后,我们讨论了如何我们的方法可以实现其他边缘变形。
We describe a method for obtaining analytic solutions corresponding to exact marginal deformations in open bosonic string field theory. For the photon marginal defor- mation we have an explicit analytic solution to all orders. Our construction is based on a pure gauge solution where the gauge field is not in the Hilbert space. We show that the solution itself is nevertheless perfectly regular. We study its gauge transformations and cal- culate some coefficients explicitly. Finally, we discuss howour method can be implemented for other marginal deformations.
