摘要:

Kiermaier等人最近发现了一个精确的立方开弦场论滚动快子解。和Schnabl。这种振荡的解决方案已被认为是由一个领域的重新定义,简单的指数滚动快子变形的边界共形理论。在后一种方法中,磁盘配分函数采用简单的形式。出于好奇,我们计算了一个振荡快子剖面的圆盘配分函数,发现结果几乎是一样的。

英文摘要:

An exact cubic open string field theory rolling tachyon solution was recently found by Kiermaier et. al. and Schnabl. This oscillatory solution has been argued to be related by a field redefinition to the simple exponential rolling tachyon deformation of boundary conformal theory. In the latter approach, the disk partition function takes a simple form. Out of curiosity, we compute the disk partition function for an oscillatory tachyon profile, and find that the result is nevertheless almost the same.
