 Elliptic and triangular flow of (anti)deuterons in Pb-Pb collisions at $\sqrt{s_{NN}}$= 5.02 TeV / ALICE Collaboration, CERN /ALICE The measurements of the (anti)deuterons elliptic flow ($v_2$) and the first measurements of triangular flow ($v_3$) in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon collisions $\sqrt{s_{NN}}$ = 5.02 TeV are presented. A mass ordering at low transverse momentum ($p_{\rm T}$) is observed when comparing these measurements with those of other identified hadrons, as expected from relativistic hydrodynamics.

 Constraining the Chiral Magnetic Effect with charge-dependent azimuthal correlations in Pb-Pb collisions at $\sqrt{\it{s}_{\mathrm{NN}}}$ = 2.76 and 5.02 TeV / ALICE Collaboration, CERN /ALICE Systematic studies of charge-dependent two- and three-particle correlations in Pb--Pb collisions at $\sqrt{\it{s}_\mathrm{{NN}}} =$ 2.76~and 5.02~TeV used to probe the Chiral Magnetic Effect (CME) are presented. These measurements are performed for charged particles in the pseudorapidity ($\eta$) and transverse momentum ($p_{\rm{T}}$) ranges $\left|\eta \right| < 0.8$ and $0.2 < p_{\mathrm{T}} < 5$~GeV/$c$.

 Measurement of isolated photon-hadron correlations in 5 TeV pp and pPb data / ALICE Collaboration, CERN /ALICE This paper presents isolated photon-hadron correlations using pp and p-Pb data collected by the ALICE detector at the LHC. For photons with |$\eta$| < 0.67 and 12 < $p_{\rm{T}}$ < 40 GeV/$c$, the associated yield of charged particles in the range |$\eta$| < 0.80 and 0.5 < $p_{\rm{T}}$ < 10 GeV/$c$ is presented.

 J/$\psi$ elliptic and triangular flow in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV / ALICE Collaboration, CERN The inclusive J/$\psi$ elliptic ($v_{2}$) and triangular ($v_{3}$) flow coefficients are measured at forward rapidity (2.5 < y < 4) and the $v_{2}$ at midrapidity (|y| < 0.9) in PbPb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV using the ALICE detector at the LHC. The entire Pb-Pb data sample collected during Run 2 is employed, amounting to integrated luminosities of about 750 $\mu\rm{b}^{-1}$ at forward rapidity and 93 $\mu\rm{b}^{-1}$ at midrapidity.

 Soft-dielectron excess in proton-proton collisions at $\sqrt{s}$ = 13 TeV / ALICE Collaboration, CERN A measurement of dielectron production in proton-proton (pp) collisions at $\sqrt{s}$ = 13 TeV, recorded with the ALICE detector at the CERN LHC, is presented in this Letter. The data set was recorded with a reduced magnetic solenoid field. [...] CERN-EP-2020-095.- Geneva : CERN, 2020 - 13. Draft (restricted): PDF;

 First measurement of quarkonium polarization in nuclear collisions at the LHC / ALICE Collaboration, CERN The polarization of inclusive J/$\psi$ and $\Upsilon(1{\rm S})$ produced in Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}=5.02$ TeV at the LHC is measured with the ALICE detector. The study is carried out by reconstructing the quarkonium through its decay to muon pairs in the rapidity region $2.5 2020-05-20 11:15  A new laboratory to study hadron-hadron interactions / ALICE Collaboration, CERN One of the big challenges for nuclear physics today is to understand, starting from first principles, the effective interaction between hadrons with different quark content. First successes have been achieved utilizing techniques to solve the dynamics of quarks and gluons on discrete space-time lattices.

It is performed in the dimuon decay channel, through the detection of muons with pseudorapidity$-4 < \eta_{\mu} < -2.5$and transverse momentum$p_{T}^{\mu} > 20$GeV/$c$in the laboratory frame.

The J/$\psi$meson yield is measured at midrapidity ($|y|<0.9$) in the dielectron channel, for events selected based on the charged-particle multiplicity at midrapidity ($|\eta|<1$) and at forward rapidity ($-3.7<\eta<-1.7$and$2.8<\eta<5.1\$); both observables are normalized to their corresponding averages in minimum bias events.
