利用LHCB实验收集的积分光度约为30nb^-1的数据，研究了在Sqrt[S NN}]=8.16TeV的质子-铅碰撞中产生的瞬发Charm-强子对。测量了不同魅力强子对的产生截面，并研究了两魅力强子之间的运动学关联。这是首次对质子-铅碰撞中两个魅力强子的联合产生进行测量。这一结果证实了与单部分子散射相比，质子-铅碰撞中双部分子散射产生的预测增强。
A study of prompt charm-hadron pair production in proton-lead collisions at sqrt[s_{NN}]=8.16 TeV is performed using data corresponding to an integrated luminosity of about 30 nb^{-1}, collected with the LHCb experiment. Production cross sections for different pairs of charm hadrons are measured and kinematic correlations between the two charm hadrons are investigated. This is the first measurement of associated production of two charm hadrons in proton-lead collisions. The results confirm the predicted enhancement of double parton scattering production in proton-lead collisions compared to the single parton scattering production.
