摘要:

本文用动量表象中的偶极方法分析了高能$pp$碰撞中$D$ -介子的产生。考虑QCD动力学的非线性行为,我们给出了$D$ -介子微分截面的横向动量和快度分布的预言。我们的结果和相应的实验测量报告的ALICE和LHCb合作在不同的快度箱之间的比较。我们证明了利用QCD偶极横动量分布可以很好地处理高能极限下的$D$ -介子产生。

英文摘要:

The production of $D$-mesons in high-energy $pp$ collisions at the LHC kinematic regime is analyzed with the dipole approach in the momentum representation. We present predictions for the $D$-meson differential cross section in terms of the transverse momentum and rapidity distributions taking into account the nonlinear behavior of the QCD dynamics. Comparison between our results and the corresponding experimental measurements reported by the ALICE and LHCb Collaborations in different rapidity bins is performed. We show that the $D$-meson production in the high energy limit can be properly addressed by using the QCD dipole transverse momentum distributions.
