光锥规范超弦场论与维数正则化

Light-Cone Gauge Superstring Field Theory and Dimensional Regularization

Yutaka Baba, Nobuyuki Ishibashi, Koichi Murakami

摘要:

我们提出了一个在光锥规范NSR超弦场论中的维度正则化方案,用来正则化由插入在相互作用点的碰撞超流引起的发散。我们研究了树的振幅,并表明我们的计划实际上正规化的分歧。我们研究了NS-NS闭弦的四点振幅,发现一次量子化理论的结果在没有任何反项的情况下得到了再现。

英文摘要:

We propose a dimensional regularization scheme in the light-cone gauge NSR superstring field theory to regularize the divergences caused by the colliding supercurrents inserted at the interaction points. We study the tree amplitudes and show that our scheme actually regularize the divergences. We examine the four-point amplitudes for the NS-NS closed strings and find that the results in the first-quantized theory are reproduced without any counterterms.
