高扭转对深度非弹性结构函数的贡献

Higher Twist Contributions to Deep-Inelastic Structure Functions

Johannes Blümlein, Helmut Böttcher

摘要:

我们报告最近提取的更高的扭曲贡献的深非弹性结构功能$F_2^{ep,ed}(x,Q^2)$在大$x$区域。结果表明,提取的高扭转贡献的大小是强烈相关的高阶修正施加到领先的扭转部分。观察到从NLO到N $^4$ LO的较高扭转贡献的逐渐降低,其中在后一种情况下,仅考虑前导大$x$项。

英文摘要:

We report on a recent extraction of the higher twist contributions to the deep inelastic structure functions $F_2^{ep,ed}(x,Q^2)$ in the large $x$ region. It is shown that the size of the extracted higher twist contributions is strongly correlated with the higher order corrections applied to the leading twist part. A gradual lowering of the higher twist contributions going from NLO to N$^4$LO is observed, where in the latter case only the leading large $x$ terms were considered.
