摘要:

SecDec是一个程序,可用于从参数积分,特别是多回路积分,以及随后的有限系数的数值计算的尺寸调节极点的因式分解。在这里,我们提出了3.0版本的程序,它有重大改进相比,版本2:它是更快,包含新的分解策略,改进的用户界面和各种其他新功能,扩大了适用范围。

英文摘要:

SecDec is a program which can be used for the factorization of dimensionally regulated poles from parametric integrals, in particular multi-loop integrals, and the subsequent numerical evaluation of the finite coefficients. Here we present version 3.0 of the program, which has major improvements compared to version 2: it is faster, contains new decomposition strategies, an improved user interface and various other new features which extend the range of applicability.
