- 論文の詳細を見る
The behaviour of the quark parton distribution functions is discussed through the phenomenological analysis of the deep inelastic e-p and e-n data under constraint of the saturation of the Adler sum rule. It is concluded that in the region 0≤x≤x_0 where the Regge parametrization can be applied, u^^-(x) is equal to d^^-(x), and both behave as const/x, (x_0 will be 0.04〜0.05); for x_0<x≤1, both u^^-(x) and d^^-(x) reduce rapidly to sufficiently small values as x increases and u^^-(x)<d^^-(x) holds; and s(x) and s^^-(x) have roughly the similar behaviour to u^^-(x) and d^^-(x). One possible explanation of u^^-(x)<d^^-(x) for x>x_0 is given. The rate of convergence of the Adler sum rule is also discussed.
