Quarks are among the elementary particles of the Standard Model of Particle Physics. Besides up and down quarks, which are the basic building blocks of ordinary matter in the Universe, four other quar...
The ALICE detector at the LHC recorded first Pb-Pb collisions at 2.76 TeV in November and December of 2010. We report on the measurements of anisotropic flow for charged and identified particles. From...
The measurements of charged-particle multiplicity and transverse energy at mid-rapidity in Pb-Pb collisions at sqrt(sNN) = 2.76 TeV are reported as a function of centrality. The fraction of the inelas...
The ALICE experiment has measured the D meson production in pp and Pb-Pb collisions at the LHC at {\surd}s = 7 and 2.76 TeV and {\surd}sNN = 2.76 TeV respectively, via the exclusive reconstruction of ...

The LHC with its unprecedented energy offers unique opportunities for groundbreaking measurements in p+p, p+A and A+A collisions even beyond the baseline experimental designs. ALICE is setting up a pr...
Charged particle directed flow at midrapidity, |eta|<0.8, and forward rapidity, 1.7 < |eta|<5.1, is measured in Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV with ALICE at the LHC. Directed flow is report...
The study of resonance production in pp collisions helps understanding hadronization mechanisms and tuning the QCD-inspired particle production models. In Pb--Pb collisions, resonances allow one to pr...
For a quantitative interpretation of reconstructed jet properties in heavy-ion collisions it is paramount to characterize the contribution from the underlying event and the influence of background flu...
We present the first results from the ALICE experiment on the nuclear modification factors for heavy-flavour hadron production in Pb-Pb collisions at sqrt{s_NN}=2.76 TeV. Using proton-proton and lead-...
据国外媒体报道,近日,欧洲粒子物理研究所大型强子对撞机ALICE实验首次实验结果发现,宇宙最初期不仅非常炽热,而且密度很大,其行为特征颇似炽热液体。
大型强子对撞机(LHC)上的大型离子对撞机实验(ALICE)将致力于TeV能区重离子碰撞,探测夸克退禁闭的新物质形态——夸克-胶子等离子体(QGP),探索宇宙诞生之初的物态性质。本文介绍其上的新一代电磁谱仪ALICE光子探测器(PHOS),它将用于铅-铅碰撞实验中测量直接光子和衰变光子产物,诊断夸克物质的电磁信号。束流测试结果显示,ALICE光子谱仪——PHOS将能够高效探测0.5~100GeV...
