常B场开弦场论中的快子真空解

Tachyon Vacuum Solution in Open String Field Theory with Constant B Field

Akira Ishida, Chanju Kim, Yoonbai Kim, O-Kab Kwon, D. D. Tolla

摘要:

我们证明了Schnabl快子真空解是Witten开玻色弦场论运动方程在常反对称二型场背景下的精确解。在真空解处计算的作用量由狄拉克-玻恩-因菲尔德因子乘以没有反对称张量场的作用量给出。

英文摘要:

We show that Schnabl's tachyon vacuum solution is an exact solution of the equation of motion of Witten's open bosonic string field theory in the background of constant antisymmetric two-form field. The action computed at the vacuum solution is given by the Dirac-Born-Infeld factor multiplied to that without the antisymmetric tensor field.
