在LHC和ALICE上的开粲介子

Open Charm Mesons at the LHC with ALICE

Renu Bala

摘要:

ALICE实验将能够在欧洲核子研究中心大型强子对撞机(LHC)的新能区中探测质子-质子和重离子碰撞中含有魅夸克和美夸克的强子。开粲介子是研究重离子碰撞中产生的介质的有力工具,因为粲夸克是在非常短的时间尺度上产生的,并且它们经历了整个碰撞历史。此外,重味产量的测量提供了一个自然的标准化的charmonia和bottomonia生产在LHC。在这次演讲中,在对ALICE的重味物理观点进行了概述之后,我们将报告一些利用蒙特卡罗模拟数据通过强子衰变通道重建D介子的研究。

英文摘要:

The ALICE experiment will be able to detect hadrons containing charm and beauty quarks in proton-proton and heavy ion collisions in the new energy regime of the CERN Large Hadron Collider (LHC). Open charmed mesons are a powerful tool to study the medium produced in heavy ion collisions, since charm quarks are produced on a very short time scale and they experience the whole history of the collision. In addition, the measurements of heavy flavour yield provide a natural normalization for those of charmonia and bottomonia production at LHC. In this talk, after a general overview of ALICE perspectives for heavy flavour physics, we will report some study of D-meson reconstruction through their hadronic decay channels with Monte Carlo simulated data.
