摘要:

本文估计了在大型强子对撞机上$pA$碰撞中双部分子散射对重夸克产生的贡献。的魅力和底部生产的截面估计使用偶极子的方法,并考虑到饱和效应,这是很重要的高能量和大的核散射。我们比较DPS的贡献与单个部分子散射的一个,并表明,在魅力生产的情况下,两者都是相似的运动学范围内探测的大型强子对撞机。LHCb协作分析的快度范围的预测也提出。我们的结果表明,在LHC上研究DPS对$pPb$碰撞中重夸克产生的贡献是可行的,并有助于探讨该方法的主要假设.

英文摘要:

In this paper we estimate the double parton scattering (DPS) contribution for the heavy quark production in $pA$ collisions at the LHC. The cross sections for the charm and bottom production are estimated using the dipole approach and taking into account the saturation effects, which are important for high energies and for the scattering with a large nucleus. We compare the DPS contribution with the single parton scattering one and demonstrate that in the case of charm production both are similar in the kinematical range probed by the LHC. Predictions for the rapidity range analysed by the LHCb Collaboration are also presented. Our results indicate that the study of the DPS contribution for the heavy quark production in $pPb$ collisions at the LHC is feasible and can be useful to probe the main assumptions of the approach.
