重味强子产生

Heavy-flavour hadron production

Mattia Faggin

摘要:

pp碰撞中重味强子产生的传统描述是基于一种因式分解的方法,假设碰撞系统之间的普遍碎裂函数。最近的结果重味重子测量从大型强子对撞机的实验表明,紧张局势与模型计算的基础上,这种方法,并采用碎裂功能限制从$\rm e^+e^-$和$\rm e^-p$碰撞实验。在这篇文章中,最新的结果ALICE,ATLAS,CMS和LHCb实验的重味强子产生的PP碰撞在TeV尺度的报告。与理论预测,解决在强子对撞机的重子增强的比较也进行了讨论。

英文摘要:

The conventional description of heavy-flavour hadron production in pp collisions is based on a factorisation approach, assuming universal fragmentation functions among collision systems. Recent results on heavy-flavour baryon measurements from the LHC experiments show tensions with model calculations based on this approach and employing fragmentation functions constrained from $\rm e^+e^-$ and $\rm e^-p$ collision experiments. In this contribution, the most recent results from ALICE, ATLAS, CMS and LHCb experiments on the heavy-flavour hadron production in pp collisions at the TeV scale are reported. The comparison with the theoretical predictions that address the baryon enhancement in hadronic collisions at the LHC is also discussed.
