 Angular correlations of heavy-flavour hadron decay electrons and charged particles in pp collisions at $\sqrt{s}$ = 5.02 TeV with ALICE at the LHC / Singh, Ravindra (Indian Inst. Tech., Indore) Two-particle azimuthal correlations of electrons from heavy-flavour hadron decays with charged particles can give insight into the properties of heavy-quark production and hadronization into heavy-flavour jets.\\ In this contribution, the ALICE results measured in pp collisions at 5.02 TeV, collected in the LHC Run 2, are presented.

 Characterization of ALPIDE silicon sensors with inclined tracks / Kushpil, Svetlana (Rez, Nucl. Phys. Inst.) /ALICE Collaboration The upgrade of the ALICE Inner Tracking System (ITS) aims at improving the capabilities of ALICE in terms of read-out rate as well as track pointing resolution and track finding efficiency, especially for particleswith low transverse momenta. The new ITS will be a low material budget detector with high granularity and read-out speed.

 Measurement of $\mathrm{D}$-meson production as a function of charged-particle multiplicity in proton--proton collisions at $\sqrt{s} = 13$ TeV with ALICE at the LHC / Bailung, Yoshini (Indian Inst. Tech., Indore) Heavy quarks (charm and beauty) are produced in hard-scattering processes and the study of their production in proton--proton (pp) collisions is an important test for calculations based on perturbative Quantum Chromodynamics (pQCD).

 Recent results on collectivity in small systems from ALICE / Khabanova, Zhanna (Nikhef, Amsterdam) /ALICE Collaboration Recent measurements performed at the LHC have revealed an unexpected presence of the near-side ridge and other signs of collectivity in p-Pb and pp collisions, referred to as small systems. Since in heavy-ion collisions these effects are caused by the formation and collective expansion of a quark-gluon plasma (QGP), such observations in small systems have triggered the ongoing debate about their origin.

 Vertexing detectors and vertexing performance in Run 2 in ALICE / Faggin, Mattia (INFN, Padua ; Padua U.) /ALICE Collaboration The ALICE apparatus includes an Inner Tracking System for high-precision vertexing and tracking at midrapidity. Thanks to this detector, remarkable results were obtained with Run 2 data in all collision systems studied at the LHC.

 Light meson nuclear modification factor in p-Pb collisions over an unprecedented $p_\mathrm{T}$ range with ALICE / Schmidt, Nicolas (Oak Ridge) /ALICE Collaboration Light neutral meson differential invariant cross section and nuclear modification factor measurements have been carried out with the ALICE detector at the CERN LHC in pp collisions at $\sqrt{s}=8$ TeV and p-Pb collisions at $\sqrt{s_\mathrm{NN}}=8.16$ TeV. The analysis combines results from several partially independent reconstruction techniques where the $\pi^0$ and $\eta$ meson decay photons were detected with the electromagnetic calorimeter, EMCal, the photon spectrometer, PHOS, or via reconstruction of $e^+e^-$ pairs from conversions in the ALICE detector material using the central tracking system. The neutral pion measurement reaching a $p_\mathrm{T}$ of 200 GeV/$c$ poses as the highest measured identified particle spectrum to date while the $\eta$ meson is measured to an unprecedented $p_\mathrm{T}$ of 50 GeV/$c$. The spectra are found to be generally overestimated by NLO pQCD calculations. The nuclear modification factors of both mesons exhibit a suppression for $p_\mathrm{T}<10$ GeV/$c$ which is stronger compared to previous measurements at $\sqrt{s_\mathrm{NN}}=5.02$ TeV and consistent with CGC and cold nuclear matter energy loss calculations.
