【摘要】 本文利用文献[1]给出的方法计算了介子结构函数。在另级近似下对于π介子有:W₁^π（x）～（1—x）。接着引入共振-雷吉修正的近似式,得到在整个区间0≤x≤1与实验相符的核子、π介子价夸克分布函数。我们还推测了标度破坏对旁观夸克数及有效袋半径的可能影响。最后指出海夸克的分布函数也可用相似的玻密修正估算。更多还原

【Abstract】 In this paper the meson structure functions are calculated by use of the method given in ref. [1]. It is obtained that W_1π（x）～ （1- x） for π-meson in the leading-order. Then an approximate expression of Resonance-Regge correction is introduced, and thus obtained nucleon and π-meson valence quark distribution functions are in good agreement with the data in the whole range, of 0≤x≤1. Also, the possible influence of scaling violation to the number of passive quarks and to the effective bag-radius is suggested. Finally, it is pointed out that the sea-quark distribution functions can be estimated by using a similar Pomeron correction.更多还原
