关于超弦论到玻色弦论约化的注记

Notes on reductions of superstring theory to bosonic string theory

Kantaro Ohmori, Yuji Tachikawa

摘要:

在微扰超弦计算中,对超黎曼曲面的奇模积分通常是非常微妙的。我们研究了这些微妙性是如何在有利的情况下消失的,包括Berkovits和Vafa关于N=0弦嵌入到N=1弦的研究,Antoniadis,Gava,Narain和Taylor以及Bershadsky,Cecotti,Ooguri和Vafa关于引力光子振幅与拓扑弦振幅的关系。黎曼曲面的模空间的Poincaré对偶在超黎曼曲面的模空间中起着重要的作用。

英文摘要:

It is in general very subtle to integrate over the odd moduli of super Riemann surfaces in perturbative superstring computations. We study how these subtleties go away in favorable cases, including the embedding of N=0 string to N=1 string by Berkovits and Vafa, and the relation of the graviphoton amplitude and the topological string amplitude by Antoniadis, Gava, Narain and Taylor and Bershadsky, Cecotti, Ooguri and Vafa. The Poincaré dual of the moduli space of Riemann surfaces in the moduli space of super Riemann surfaces plays an important role.
