Collectivity in small and large collision systems at the LHC with ALICE / Gajdošová, Katarína Křížková (Prague, Tech. U.) /ALICE Collaboration
Interactions of protons (pp) or of a proton with a lead nucleus (p–Pb) were not expected to form a deconfined hot and dense matter, called the Quark-Gluon Plasma (QGP), which is instead produced in heavy-ion collisions. However, high-multiplicity events in small collision systems exhibit signs of collectivity, which are understood as a signature of the QGP emergence in heavy-ion collisions. [...]

Highlights of the production of (anti-)(hyper-)nuclei and exotica with ALICE at the LHC / Dönigus, Benjamin (Frankfurt U., Inst. Kernphys.) /ALICE Collaboration
Measurements of the production of light (anti-)nuclei and (anti-)hypernuclei have been performed in different colliding systems at the LHC, namely pp, p–Pb and Pb–Pb. The results of the production in Pb–Pb collisions of light (anti-)(hyper-)nuclei follows the expectation of the thermal model, whereas the production of nuclei in pp and p–Pb collisions shows a closer agreement with the expectations from coalescence models.

The ALICE Inner Tracker System Upgrade / Ronchetti, Federico (Frascati) /ALICE Collaboration
The phase II upgrade of the Large Hadron Collider (LHC) at CERN is planned under the assumption that the LHC will progressively increase the luminosity of heavy ion beams, eventually reaching an interaction rate of about 50 kHz in Pb-Pb collisions, i.e. instantaneous luminosities of L = 6 × 1027 cm−2s−1.

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. [...]
