چکیده
Measurements of inclusive jet production are performed in pp and Pb+Pb collisions at √(s)NN=2.76 TeV with the ATLAS detector at the LHC, corresponding to integrated luminosities of 4.0 and 0.14 nb(-1), respectively. The jets are identified with the anti-k(t) algorithm with R=0.4, and the spectra are measured over the kinematic range of jet transverse momentum 32<p(T)<500 GeV and absolute rapidity |y|<2.1 and as a function of collision centrality. The nuclear modification factor R(AA) is evaluated, and jets are found to be suppressed by approximately a factor of 2 in central collisions compared to pp collisions. The R(AA) shows a slight increase with p(T) and no significant variation with rapidity.

Measurements of charged particle spectra and nuclear modification factor in p+Pb collisions with the ATLAS detector
The ATLAS detector at the LHC obtained the sample of p+Pb data at √ sNN = 5.02 TeV with integrated luminosity of 25 nb−1, which can be compared to the pp data obtained by interpolating pp measurements at √ s = 2.76 TeV and 7 TeV. Due to the excellent capabilities of the ATLAS detector, and its stable operation in heavy ion as well as proton–proton physics runs, the data allow measurements of th...

We report on the latest results on heavy-flavour and J/ψ production at both midrapidity and forward rapidity, in Pb–Pb collisions at √ sNN = 2.76 TeV, measured with the ALICE experiment at the LHC. We present measurements of the nuclear modification factor for open heavy-flavours and J/ψ and compare these results to model predictions. Preliminary results on the elliptic flow of D mesons and J/ψ...
