概要
- 論文の詳細を見る
The divergent sum rules derived from the current anticommutator on the null-plane are regularized by the analytical continuation from the non-forward direction. The finite part of the sum rule is shown to have one ambiguity which depends on the dynamics. The Gottfried sum rule for (F_2^<ep> - F_2^<en>) becomes free of this ambiguity if we sacrifice the consistency with the leading logarithmic approximation at the two loops in QCD. Then by the same approximation as above we obtain new sum rules from the finite parts of the sum rules.
