我们通过对双对数近似应用维度正则化，计算了在改进的最小减法（(MS) over bar）方案中对半包含强子产生的横截面的完整双对数贡献。该方案首次获得了 e(+)e(-) 湮灭中强子产生的全双对数对系数函数的贡献。我们的结果与文献中的所有固定顺序结果一致，这些结果扩展到下一个到下一个领先顺序。 (C) 2011 Elsevier B.V. 保留所有权利。
We calculate the complete double logarithmic contribution to cross sections for semi-inclusive hadron production in the modified minimal-subtraction ((MS) over bar) scheme by applying dimensional regularization to the double logarithm approximation. The full double logarithmic contribution to the coefficient functions for inclusive hadron production in e(+)e(-) 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-to-next-to-leading order. (C) 2011 Elsevier B.V. All rights reserved.
