AI中文摘要:
我们利用边界态形式研究两个 D0-膜散射过程中无质量闭弦态的发射。我们计算了玻色弦理论和 II 型超弦理论中引力子和膨胀子发射对应的五点振幅,并分析了其场论极限。对于非零碰撞参数,所得振幅可由相应低能理论的世界线表述中的独立计算重现。
英文摘要:
We study the emission of a massless closed-string state in the scattering of two D0-branes using the boundary-state formalism. We compute the corresponding five-point amplitudes for graviton and dilaton emission in bosonic string theory and in type II superstring theory, and analyze their field-theory limit. For nonzero impact parameter, the resulting amplitudes are reproduced by an independent calculation in the worldline formulation of the corresponding low-energy theory.
