论文摘要
在本文中，我们通过针对最近的H1-Zeus对深度无弹性散射（包括偶极振幅中的重夸克）进行测试，回顾和更新Amaral Gay Ducati-Betemps-Betemps-Soyez饱和模型。我们获得了该模型基于Balitsky-Kovchegov方程式并在动量空间框架中构建的模型，对减少的横截面的描述非常准确，$σ_{r}（x，y，y，y，q^{2}）$以及诸如$ f_ {2}（x，q^^^$ f _ {2} $ {2，Q，Q^^^^） $ f_ {l}（x，q^{2}）$，全部以HERA测量。此外，它提供了重夸克结构功能的良好描述，$ f_ {2}^{cc} $和$ f_ {2}^{bb} $在small- $ x $和$ x $和$ q^{2} \ sillesim 60 $ gev $^$^{2} $。我们还使用改进的模型来预测在不久的将来在LHEC衡量的结构函数。
In this paper we review and update the Amaral-Gay Ducati-Betemps-Soyez saturation model, by testing it against the recent H1-ZEUS combined data on deep inelastic scattering, including heavy quarks in the dipole amplitude. We obtain that this model, which is based on traveling wave solutions of the Balitsky-Kovchegov equation and built in the momentum space framework, yields very accurate descriptions of the reduced cross section, $σ_{r}(x,y,Q^{2})$, as well as DIS structure functions such as $F_{2}(x,Q^{2})$ and $F_{L}(x,Q^{2})$, all measured at HERA. Additionally, it provides good descriptions of heavy quark structure functions, $F_{2}^{cc}$ and $F_{2}^{bb}$ at small-$x$ and $Q^{2}\lesssim 60$ GeV$^{2}$. We also use the improved model to make predictions for structure functions to be measured in the near future at LHeC.
