带电电流在三圈处的深度非弹性散射

Charged current deep-inelastic scattering at three loops

S. Moch, M. Rogal

摘要:

本文导出了nu P - nubar P组合中中微子-质子深度非弹性散射的带电电流结构函数F_2、F_L和F_3对三个圈的微扰QCD修正。在首扭近似下,我们计算了F_2和F_L的前五个奇整数Mellin矩和F_3的前五个偶整数Mellin矩。作为一个新的结果,我们得到了O(α_s^3)的系数函数,而相应的反常维数与文献中的已知结果一致。

英文摘要:

We derive for deep-inelastic neutrino-proton scattering in the combination nu P - nubar P the perturbative QCD corrections to three loops for the charged current structure functions F_2, F_L and F_3. In leading twist approximation we calculate the first five odd-integer Mellin moments in the case of F_2 and F_L and the first five even-integer moments in the case of F_3. As a new result we obtain the coefficient functions to O(alpha_s^3) while the corresponding anomalous dimensions agree with known results in the literature.
