摘要:

通过将维数正则化应用到双对数近似中,计算了半包含强子产生在修正的最小减法方案中的完全双对数对截面的贡献.在这个方案中,首次得到了电子正电子湮没中包含强子产生系数函数的全双对数贡献。我们的结果与文献中所有固定阶的结果一致,并推广到了次次领先阶。

英文摘要:

We calculate the complete double logarithmic contribution to cross sections for semi-inclusive hadron production in the modified minimal-subtraction scheme by applying dimensional regularization to the double logarithm approximation. The full double logarithmic contribution to the coefficient functions for inclusive hadron production in electron-positron annihilation is obtained in this scheme for the first time. Our result agrees with all fixed order results in the literature, which extend to next-next-to-leading order.
