After the successful start of Run 3 in July this year, which featured proton-proton collisions at the record energy of 13.6 TeV, it was the turn of lead nuclei to circulate in the Large Hadron Collide...
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 CERN CRANEbot is seen here carrying a VAX module (centre of the image) inside the CMS cavern, as part of an operation test conducted in early February 2021. The robot, which has been developed at ...
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 transverse momentum spectra, elliptic flow and interferometry radii for Pb-Pb collisions at the LHC are calculated in relativistic viscous hydrodynamics. For Glauber model initial conditions, we f...
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 Color String Percolation Model (CSPM) is used to determine the shear viscosity to entropy ratio ($\eta/s$) of the Quark-Gluon Plasma (QGP) produced in Au-Au collisions at $\sqrt{s_{NN}}$ = 200 GeV...
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-...
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...
