论文摘要
$ D $ - 米森的生产是通过考虑动量代表中偶极子方法中未集成的Gluon分布来研究的。我们分析了$ d $ -Meson Spectrum核算QCD动力学的非线性行为的影响，QCD动力学可以在偶极框架中解决。通过使用几何缩放特性获得了不整合的Gluon分布，并将结果与Glauber-Gribov框架进行了比较。研究了绝对横向动量光谱和核修饰比。将预测与Alice和LHCB合作的实验测量进行了比较，以$ pa $碰撞的不同速度箱。
The $D$-meson production is investigated by considering the unintegrated gluon distribution within the dipole approach in the momentum representation. We analyze the $D$-meson spectrum accounting for the effects of nonlinear behavior of the QCD dynamics which can be accordingly addressed in the dipole framework. The unintegrated gluon distribution is obtained by using geometric scaling property and the results are compared to the Glauber-Gribov framework. The absolute transverse momentum spectra and the nuclear modification ratios are investigated. Predictions are compared with the experimental measurements by the ALICE and LHCb Collaborations in $pA$ collisions for different rapidity bins.
