摘要:

本文通过求解Dokshitzer-Gribov-Lipatov-Altarelli-Parisi发展方程,在小x极限下,得到了自旋相关的单重态和非单重态结构函数。在这里,我们使用泰勒级数展开,然后特殊的和唯一的解决方案,以解决发展方程。计算了氘、质子和中子的结构函数,并与SLAC E-143合作组的数据进行了比较。

英文摘要:

In this paper the spin-dependent singlet and nonsinglet structure functions have been obtained by solving Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution equations in leading order in the small x limit. Here we have used Taylor series expansion and then the particular and unique solution to solve the evolution equations. We have also calculated t evolutions of deuteron, proton and neutron structure functions and the results are compared with the SLAC E-143 Collaboration data.
