在LHC上用ALICE测量重味强子衰变和轻强子衰变的电子之间的相关

Measurements of the correlation between electrons from heavy-flavour hadron decays and light hadrons with ALICE at the LHC

E. Pereira De Oliveira Filho

摘要:

在相对论重离子物理中,两粒子关联为研究夸克-胶子等离子体(QGP)提供了一个非常有用的工具。这个观测值对QGP的几个性质很敏感,例如共振,部分子与介质的相互作用和集体效应(e。G.椭圆流)。本文测量了pp和Pb-Pb碰撞(中心和半中心)中重味强子衰变电子与轻强子电子之间的关联函数。此外,在pp碰撞的相对美丽的贡献,从重味衰变的电子总截面估计通过比较测量的相关性与蒙特卡罗模板。

英文摘要:

In relativistic heavy-ion physics two-particle correlations provide a very useful tool to investigate the Quark-Gluon Plasma (QGP). This observable is sensitive to several of the properties of the QGP such as resonances, interaction of partons with the medium and collective effects (e. g. elliptic flow). In the present work, the correlation function between electrons from heavy-flavour hadron decays and light hadrons was measured in pp and Pb-Pb collisions (central and semi-central). Furthermore, in pp collisions the relative beauty contribution to the total cross section of electrons from heavy-flavour decays was estimated by comparing the measured correlation with Monte-Carlo templates.
