Veneziano and Shapiro-Virasoro amplitudes of arbitrarily excited strings

Maurizio Firrotta

AI总结:

本文基于相干弦态形式体系,将Veneziano和Shapiro-Virasoro振幅推广至玻色弦理论中的任意激发态,并推导了三弦相互作用的协变形式及连接开闭弦散射的广义Kawai-Lewellen-Tye关系。

摘要:

我们将Veneziano和Shapiro-Virasoro振幅推广至玻色弦理论中的四个任意激发态。我们使用基于Di Vecchia-Del Giudice-Fubini构造的相干弦态形式体系。在同一形式体系内,我们还分析了三弦散射,找到了三Reggeon相互作用的协变版本。接着通过研究扩展的四弦散射振幅的因子化性质,我们确定了三弦相互作用的协变版本。最后,我们得到了连接四个任意激发态的开放弦与闭合弦散射的广义Kawai-Lewellen-Tye关系。

英文摘要:

We extend the Veneziano and Shapiro-Virasoro amplitudes to four arbitrarily excited states in bosonic string theory. We use the formalism of coherent string states based on the Di Vecchia-Del Giudice-Fubini construction. Within the same formalism, we also analyze the three string scattering finding the covariant version of the three reggeon interaction. Then studying the factorization properties of the extended four string scattering amplitudes we identify the covariant version of the three string interaction. Finally we obtain generalized Kawai-Lewellen-Tye relations connecting the scattering of four open and closed arbitrarily excited states.
