title: "Table 1" of "Measurement of $\Upsilon(1{\rm S})$ elliptic flow at forward rapidity in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}=5.02$ TeV"

description: The J/$\psi$ $v_2$ coefficient as a function of $p_{\rm T}$ in 5-60% centrality interval in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV.
description: CERN-LHC-ALICE. The first measurement of the $\Upsilon(1{\rm S})$ elliptic flow coefficient ($v_2$) is performed at forward rapidity (2.5 &lt; $y$ &lt; 4) in Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV with the ALICE detector at the LHC. The results are obtained with the scalar product method and are reported as a function of transverse momentum ($p_{\rm T}$) up to 15 GeV/$c$ in the 5--60\% centrality interval. The measured $\Upsilon(1{\rm S})$ $v_2$ is consistent with zero and with the small positive values predicted by transport models within uncertainties. The $v_2$ coefficient in 2 &lt; $p_{\rm T}$ &lt; 15 GeV/$c$ is lower than that of inclusive J/$\psi$~mesons in the same $p_{\rm T}$ interval by 2.6 standard deviations. These results, combined with earlier suppression measurements, are in agreement with a scenario in which the $\Upsilon$(1S) production in Pb--Pb collisions at LHC energies is dominated by dissociation limited to the early stage of the collision whereas in the J/$\psi$ case an additional regeneration component is possibly present.

description: $p_{\rm T}$-integrated inclusive J/$\psi$ cross section.
description: CERN-LHC. Inclusive J/$\psi$ production is studied in minimum-bias proton-proton collisions at a centre-of-mass energy of $\sqrt{s} = 5.02$ TeV by ALICE at the CERN LHC. The measurement is performed at mid-rapidity ($|y| &lt; 0.9$) in the dielectron decay channel down to zero transverse momentum $p_{\rm T}$, using a data sample corresponding to an integrated luminosity of $19.4 \pm 0.4 $ nb$^{-1}$. The measured $p_{\rm T}$-integrated inclusive J/$\psi$ production cross section is $\text{d}\sigma/\text{d}y = 5.64 \pm 0.22 (\text{stat.}) \pm 0.33 (\text{syst.}) \pm 0.12 (\text{lumi.})$ $\mu$b. The $p_{\rm T}$-differential cross section $\text{d}^2\sigma/\text{d}p_{\rm T}\text{d}y$ is measured in the $p_{\rm T}$ range 0$-$10 GeV/$c$ and compared with state-of-the-art perturbative QCD calculations. The J/$\psi$ $\langle p_{\rm T} \rangle$ and $\langle p_{\rm T}^2 \rangle$ are extracted and compared with results obtained at other collision energies.

title: "Table 0" of "Measurement of jet fragmentation in Pb+Pb and $pp$ collisions at $\sqrt{s_{NN}} = 5.02$ TeV with the ATLAS detector"

description: The D(z) distributions in different centrality intervals in PbPb and in pp for 126.00 &lt; pTjet &lt; 158.49 and 0.0 &lt; eta &lt; 2.1.
description: CERN-LHC. This paper presents a measurement of jet fragmentation functions in 0.49 nb−1 of Pb+Pb collisions and 25 pb−1 of pp collisions at sNN=5.02 TeV collected in 2015 with the ATLAS detector at the LHC. These measurements provide insight into the jet quenching process in the quark-gluon plasma created in the aftermath of ultrarelativistic collisions between two nuclei. The modifications to the jet fragmentation functions are quantified by dividing the measurements in Pb+Pb collisions by baseline measurements in pp collisions. This ratio is studied as a function of the transverse momentum of the jet, the jet rapidity, and the centrality of the collision. In both collision systems, the jet fragmentation functions are measured for jets with transverse momentum between 126 and 398 GeV and with an absolute value of jet rapidity less than 2.1. An enhancement of particles carrying a small fraction of the jet momentum is observed, which increases with centrality and with increasing jet transverse momentum. Yields of particles carrying a very large fraction of the jet momentum are also observed to be enhanced. Between these two enhancements of the fragmentation functions a suppression of particles carrying an intermediate fraction of the jet momentum is observed in Pb+Pb collisions. A small dependence of the modifications on jet rapidity is observed.
