具有任意质量的双环日出图

The two-loop sunrise graph with arbitrary masses

Luise Adams, Christian Bogner, Stefan Weinzierl

摘要:

讨论了两个时空维中具有任意非零质量的双环日出图的解析解。通过求解一个二阶微分方程得到了解析结果。该解决方案涉及椭圆积分,特别是相应的齐次微分方程的解决方案是由椭圆曲线的周期。

英文摘要:

We discuss the analytical solution of the two-loop sunrise graph with arbitrary non-zero masses in two space-time dimensions. The analytical result is obtained by solving a second-order differential equation. The solution involves elliptic integrals and in particular the solutions of the corresponding homogeneous differential equation are given by periods of an elliptic curve.
