Elisa Meninno

摘要:

本文介绍了ALICE关于粲重子产生的最新结果。特别是测量的$Λ_{\rm c}^{+}$ -重子生产在pp碰撞在${\sqrt{\rm s}}$ = 5.02 TeV和p-Pb碰撞在$\sqrt{\rm s_{NN}}$ = 5.02 TeV的显示和比较与以前的测量使用pp和p-Pb数据样本收集在LHC运行1。在中快度的魅力重子重建通过他们的强子衰变和半轻子衰变通道,利用高精度跟踪,优秀的顶点和粒子识别能力提供的ALICE探测器。还给出了在$\sqrt{\rm s_{NN}}$ = 5.02 TeV的Pb-Pb碰撞中$Λ_{\rm c}^{+}$重子产生的首次测量结果。结果与理论预期进行了比较。

英文摘要:

In this contribution, the latest ALICE results on charmed baryon production are presented. In particular the measurements of $Λ_{\rm c}^{+}$-baryon production in pp collisions at ${\sqrt{\rm s}}$ = 5.02 TeV and in p-Pb collisions at $\sqrt{\rm s_{NN}}$ = 5.02 TeV are shown and compared with previous measurements performed using pp and p-Pb data samples collected during LHC Run 1. At mid-rapidity charmed baryons are reconstructed via their hadronic decay and semileptonic decay channels, exploiting the high precision tracking, excellent vertexing and particle identification capabilities offered by the ALICE detector. The first measurement of $Λ_{\rm c}^{+}$-baryon production in Pb-Pb collisions at $\sqrt{\rm s_{NN}}$ = 5.02 TeV is also shown. Results are compared with theoretical expectations.
