Jet fragmentation in two-particle correlations in pp, p–Pb and Pb–Pb collisions / Vargyas, Marton (Jyvaskyla U. ; Helsinki Inst. of Phys.) /ALICE Collaboration
The per-trigger normalized associated particle yield as a function of the pseudorapidity difference ($\Delta\eta{}$) was measured in Pb-Pb and pp collisions at $\sqrt{s_{\rm NN}}$~=~2.76 TeV. For the transverse momentum of the trigger hadron $8<p_{\rm T,trig}<15$ GeV/$c$ and the associated hadron $6<p_{\rm T,assoc}<8$ GeV/$c$ it is observed that the near side peak is narrower in central Pb-Pb collisions relative to the pp results.

Future upgrades of ALICE for Run 4 / Krizek, Filip (Rez, Nucl. Phys. Inst.) /ALICE Collaboration
The ALICE Collaboration is preparing two upgrades for installation during LHC Long Shutdown 3. The first project is the replacement of the inner barrel of the Inner Tracking System (ITS) detector with cylindrical layers based on large-scale, wafer-sized, bent, monolithic active pixel sensors. [...]

Production of light nuclei in small collision systems measured with ALICE / Balbino, Alessandro (Polytech. Turin ; INFN, Turin) /ALICE Collaboration
The energy densities reached in high-energy hadronic collisions at the LHC allow significant production of light (anti)nuclei. Their production yields have been measured as a function of $p_\mathrm{T}$ and charged-particle multiplicity in the ALICE detector for different collision systems and at different center-of-mass energies.

Charm cross section and fragmentation fractions in pp collisions with ALICE / Dello Stritto, Luigi (Salerno U.) /ALICE Collaboration
In this contribution, the latest $\rm \Lambda_c$, $\rm \Xi_{c}^{0}$ and the first $\rm \Xi_{c}^{+}$, $\rm \Sigma_{c}^{0,++}$ and $\rm \Omega_{c}^{0}$ baryon measurements performed with the ALICE detector at midrapidity in proton--proton collisions at $\sqrt{s}=5.02\,$TeV and $13\,$TeV at the LHC are presented. Recent measurements of baryon-to-meson cross-section ratios at midrapidity show significantly higher results than in $\rm e^{+}e^{-}$ and ep collisions, suggesting that the fragmentation of charm is not universal across different collision systems.

Upgrade of pixel sensor telescope for the characterization of ALPIDE sensor / Kaewjai, J (Suranaree U. of Tech.) ; Kobdaj, C (Suranaree U. of Tech.) ; Kittimanapun, K (NSRC, Nakhon Ratchasima)
A Large Ion Collider Experiment (ALICE) is an experiment station at CERN that detects quark-gluon plasma, a state of matter thought to have formed immediately after the big bang. A plan was proposed to upgrade the particle detector in the Inner Tracking System (ITS) of ALICE by 2020. [...]

Measurement of $\Lambda_c^+$ production in pp and p-Pb collisions with the ALICE experiment at the LHC / Bartels, Clara (Liverpool U.) /ALICE Collaboration
Heavy-flavour measurements in pp and p--Pb collisions are crucial to investigate charm hadronisation mechanisms. This contribution presents the recent measurements of the $\Lambda_\text{c}^+$ production cross section, the $\Lambda_\text{c}^+/\text{D}^0$ ratio, and the nuclear modification factor in p--Pb collisions, including the new measurements of $\Lambda_\text{c}^+$ production down to $p_\text{T} = 0$ in p--Pb collisions at $\sqrt{s_\text{NN}}=$ 5.02 TeV with the ALICE experiment at the LHC..

Status of the Fast Interaction Trigger detector for the ALICE upgrade / Rojas Torres, Solangel (CTU, Prague) /ALICE Collaboration
During the second Long Shutdown (LS2) of the LHC, ALICE has installed three new detectors and implemented continuous data readout with online reconstruction and data compression for several other subsystems. The changes are needed to benefit from the increased luminosity of the LHC during Run 3 and 4. [...]

Underlying Event studies and search for jet modifications in pp and p-Pb collisions with ALICE at the LHC / Mehmood Khan, Ahsan (Hua-Zhong Normal U., LQLP ; CCNU, Wuhan, Inst. Part. Phys.) /ALICE Collaboration
It is well-established that high-multiplicity pp and p--Pb collisions exhibit various signatures associated with the formation of QGP in heavy-ion collisions. In this contribution, we present results obtained using Underlying Event (UE) techniques, used to measure the average number density and the average total transverse momentum ($p_{\rm T}$) in the Transverse region with respect to the leading trigger particle, but employed in novel ways.

Preparation for ALICE data processing and analysis in LHC Run 3 / Eulisse, Giulio (CERN) /ALICE Collaboration
After the ALICE Long Shutdown 2 detector upgrades, including a new silicon tracker and a GEM-based readout for the TPC, the experiment will operate during LHC Run 3 at a peak Pb-Pb collision rate of 50 kHz, about 50 times higher than in previous running periods. To maximise the significance of physics signals with low S/B ratios for which triggering is not possible, all events will be read out and written to permanent storage without any selective trigger.
