论文摘要
我们表明，可以使用标准DGLAP扰动进化来解释偶极横截面的几何缩放。通过依靠$ f_ {2}（x，q^{2}）$的froissart-oundaughtagiations参数化，考虑了在LO和NNLO近似值的DGLAP改进的饱和模型。这些结果可与Golec-Biernat-w $ \ ddot {\ Mathrm {u}} $ sthoff（GBW）模型中的golec-biernat-w $ \ ddot相提并论，该模型在宽的运动区域$ rq_ {s} $中，它考虑了魅力质量。 $σ_{\ Mathrm {Dip}}}（x，r）/σ_{0} $和$σ_{\ Mathrm {Dip}}（rq_ {s}）/σ_{0} $的成功描述。
We show that the geometric scaling of the dipole cross section can be explained using standard DGLAP perturbative evolution. The DGLAP improved saturation model due to the Laplace transforms method is considered at LO and NNLO approximations from the experimental data by relying on a Froissart-bounded parametrization of $F_{2}(x,Q^{2})$. These results are comparable with Golec-Biernat-W$\ddot{\mathrm{u}}$sthoff (GBW) model in a wide kinematic region $rQ_{s}$ which takes into account charm mass. The successful description of $σ_{\mathrm{dip}}(x,r)/σ_{0}$ and $σ_{\mathrm{dip}}(rQ_{s})/σ_{0}$ are presented.
