Running ALICE Grid Jobs in Containers : A new approach to job execution for the next generation ALICE Grid framework / Storetvedt, Maxim (HVL, Norway) ; Betev, Latchezar (CERN) ; Helstrup, Håvard (HVL, Norway) ; Hetland, Kristin Fanebust (HVL, Norway) ; Kileng, Bjarte (HVL, Norway) /ALICE Collaboration
The new JAliEn (Java ALICE Environment) middleware is a Grid framework designed to satisfy the needs of the ALICE experiment for the LHC Run 3, such as providing a high-performance and high-scalability service to cope with the increased volumes of collected data. This new framework also introduces a split, two-layered job pilot, creating a new approach to how jobs are handled and executed within the Grid. [...]

Fast Entropy Coding for ALICE Run 3 / Lettrich, Michael /ALICE Collaboration
In LHC Run 3, the upgraded ALICE detector will record Pb-Pb collisions at a rate of 50 kHz usingcontinuous readout. The resulting stream of raw data at 3.5 TB/s has to be processed with a setof lossy and lossless compression and data reduction techniques to a storage data rate of 90 GB/swhile preserving relevant data for physics analysis.

ALICE : online-offline processing for Run 3 / Rohr, David (CERN) /ALICE Collaboration
ALICE will increase the data-taking rate for Run 3 significantly to 50 kHz continuous readout of minimum bias Pb--Pb collisions. The foreseen reconstruction strategy consists of 2 phases: a first synchronous online reconstruction stage during data-taking enabling detector calibration, and a posterior calibrated asynchronous reconstruction stage. [...]

Data Analysis using ALICE Run 3 Framework / Eulisse, Giulio (CERN) ; Alkin, Anton (BITP, Kiev) ; Grosse-Oetringhaus, Jan Fiete (CERN) ; Hristov, Peter (CERN ; Warsaw U. of Tech.) ; Innocenti, Gian Michele (CERN) ; Kabus, Maja Jadwiga (Warsaw U. of Tech.)
The ALICE Experiment is currently undergoing a major upgrade program, both in terms of hardware and software, to prepare for the LHC Run 3. A new Software Framework is being developed in collaboration with the FAIR experiments at GSI to cope with the 100-fold increase in the number of recorded events. [...]

Spin alignment measurements of vector mesons with ALICE at the LHC / Kundu, Sourav (NISER, Jatni) /ALICE Collaboration
We report the first measurements of spin alignment of K *0 and ϕ vector mesons (spin = 1) in heavy-ion collisions at LHC energies. Measurements are carried out with the ALICE detector in Pb–Pb collisions at sNN=2.76TeV . [...]

Event shape dependence of anisotropic flow for inclusive and identified hadrons in Pb–Pb and Xe–Xe collisions with ALICE / Besoiu, M (Bucharest, Inst. Space Science) /ALICE Collaboration
Event Shape Engineering technique has been used to select events corresponding to a specific initial geometry in a given centrality class. For those events, the elliptic ( ν 2 ) and triangular ( ν 3 ) flow coefficients of inclusive as well as identified particles, including π ± , K ± , p+p‾ , KS0 , Λ+Λ‾ , and Ξ−+Ξ‾+ are measured in Pb–Pb collisions at sNN=5.02TeV recorded by ALICE.

First experimental test of HAL QCD lattice calculations for the multi strange hyperon - nucleon interaction with ALICE / Mihaylov, Dimitar Lubomirov (Munich, Tech. U.) /ALICE Collaboration
The use of non-traditional femtoscopy in small collision systems is a promising technique to improve our knowledge on nucleon-hyperon and hyperon-hyperon interactions. This article gives an overview on the experimental status and prospects for the measurement of the p–Ξ − and p–Ω − correlation functions, using the ALICE data collected in pp collisions at 13 TeV, triggered for high-multiplicity.

Latest results on $\Lambda^+_c$ and D production in pp and Pb-Pb collisions at $\sqrt {s_{NN}}$ = 5.02TeV with ALICE at the LHC / Innocenti, Gian Michele (CERN) /ALICE Collaboration
The measurement of heavy-flavour production is a powerful tool to study the medium formed in high-energy heavy-ion collisions. Produced in hard scattering processes on a timescale shorter than the formation time of the Quark Gluon Plasma (QGP), they experience the whole evolution of the medium interacting with its constituents.

Measurement of long-range two- and multi-particle correlations by ALICE / Sekiguchi, Yuko (Tokyo U., CNS) /ALICE Collaboration
Measurements of long-range particle correlations provide critical insights into the properties of the strongly coupled matter created in heavy-ion collisions and even in small collision systems, such as pp and p–Pb collisions. New results on long-range two-particle correlations for different multiplicity classes and ν 2 ( η ) in p–Pb collisions at 5.02 TeV are presented. [...]

Recent results on azimuthal anisotropies of open heavy-flavour particles with ALICE at the LHC / Tang, Siyu (Hua-Zhong Normal U. ; Clermont-Ferrand U.) /ALICE Collaboration
Heavy quarks are unique probes to investigate the properties of the Quark-Gluon Plasma (QGP) formed in ultra-relativistic heavy-ion collisions. The ALICE Collaboration measured the D -meson elliptic flow, ν 2 , in Pb–Pb collisions at sNN=5.02TeV to study the participation of the low and intermediate transverse momentum ( p T ) charm quarks in the collective expansion of the system.
