摘要:

考虑了杂化弦论理论中四引力子和两引力子-两胶子振幅的低动量展开,分析了四引力子振幅对D^2 R^4相互作用和两引力子-两胶子振幅对D^4 R^2 F^2相互作用的贡献.计算是通过获得方程的相关模块化的图功能,出现在模块化不变积分,并涉及合并技术中使用的II型理论和计算的椭圆属杂种优势理论。

英文摘要:

We consider the low momentum expansion of the four graviton and the two graviton--two gluon amplitudes in heterotic string theory at one loop in ten dimensions, and analyze contributions upto the D^2 R^4 interaction from the four graviton amplitude, and the D^4 R^2 F^2 interaction from the two graviton--two gluon amplitude. The calculations are performed by obtaining equations for the relevant modular graph functions that arise in the modular invariant integrals, and involve amalgamating techniques used in the type II theory and the calculation of the elliptic genus in the heterotic theory.
