标量箱积分与Mellin-Barnes表示

The scalar box integral and the Mellin - Barnes representation

Paolo Valtancoli

摘要:

我们使用Mellin-Barnes表示精确求解标量盒积分。首先,我们认识到,超几何函数,从标量积分的系列,然后我们进行解析延拓之前,应用洛朗展开^2 =(d!' 4)=结果的2。

英文摘要:

We solve exactly the scalar box integral using the Mellin-Barnes representation. Firstly we recognize the hypergeometric functions resumming the series coming from the scalar integrals, then we perform an analytic continuation before applying the Laurent expansion in^2 = (d !' 4)=2 of the result.
