用SecDec计算大量多圈积分

Numerical evaluation of massive multi-loop integrals with SecDec

Sophia Borowka, Gudrun Heinrich

摘要:

程序包SecDec,允许多回路积分的数值计算。版本1.0对欧几里德运动学的限制已经解除:阈值可以通过将积分轮廓自动变形到复平面来处理。该程序的其他新功能,这超出了标准的循环积分分解,也进行了说明。该程序可在http://secdec.hepforge.org上公开获取。

英文摘要:

The program package SecDec is presented, allowing the numerical evaluation of multi-loop integrals. The restriction to Euclidean kinematics of version 1.0 has been lifted: thresholds can be handled by an automated deformation of the integration contour into the complex plane. Other new features of the program, which go beyond the standard decomposition of loop integrals, are also described. The program is publicly available at http://secdec.hepforge.org.
