 Performance of the ALICE HMPID detector during the LHC run period 2010$-$2015 and perspectives /ALICE Collaboration In this note the performance of the ALICE High Momentum Particle IDentification (HMPID) detector during the LHC run period 2010$-$2015 is presented. The HMPID extends the charged hadron identification capability of the ALICE apparatus at high momenta, identifying with three sigma separation power charged pions and kaons in the momentum range 1$-$3 GeV/$c$ and (anti-)protons in the range 1.5$-$5 GeV/$c$.

 ALICE 2016-2017-2018 luminosity determination for pp collisions at $\mathbf{\sqrt{{\textit s}}}$ = 13 TeV /ALICE Collaboration Luminosity determination in ALICE is based on the measurement of visible cross sections in van der Meer (vdM) scans. In the Run 2 (2015--2018), the Large Hadron Collider provided proton-proton collisions at a centre-of-mass energy of $\hbox{$\sqrt{s} = 13$TeV}$.

 ALICE physics projections for a short oxygen-beam run at the LHC /ALICE Collaboration This document collects performance projections for a selection of measurements that can be carried out with a short O$-$O run during the LHC Run 3. The baseline centre-of-mass energy per nucleon$-$nucleon collision is $\sqrt{s_{\rm NN}}=6.37$ TeV and measurement uncertainties are given for the integrated luminosity $L_{\rm int}= 1$ nb$^{-1}$.

 Signal extraction in the analysis of $\omega$ and $\phi$ meson production at forward rapidity in pp collisions at the LHC /ALICE Collaboration This note contains details on the technique used for the signal extraction in the low-mass dimuon analyses in the rapidity range $2.5 2021-03-29 17:17  Physics Preliminary Summary: Measurement of the primary Lund plane density in pp collisions at$\sqrt{s} = \rm{13}$TeV with ALICE /ALICE Collaboration A measurement of the primary Lund plane density in pp collisions at ALICE is presented. The Lund plane is built for inclusive charged-particle jets in the transverse momentum range of$20 \leq p_{\rm{T,jet}}^{\rm ch} \leq 120$GeV$/c$using an integrated luminosity$L_{\rm{int}} \approx 22.55$nb$^{-1}$recorded in minimum bias data for pp collisions at$\sqrt{s} =$13 TeV [...] ALICE-PUBLIC-2021-002.- Geneva : CERN, 2021 - 18.

In 2015 and 2018, the Large Hadron Collider provided \PbPb collisions at a centre-of-mass energy per nucleon pair of$\sqrt{s_{\rm{NN}}}$= 5.02 TeV.

In this publication, the nuclear modification factor$R_{\rm AA}$of muons from heavy-flavour hadron decays in the forward rapidity interval ($2.5 < y < 4$) is measured as a function of transverse momentum$p_{\rm T}$in central (0-10%), semi-central (20-40%) and peripheral (60-80%) centrality classes in the interval$3 < p_{\rm T}< 20$GeV/$c$.

With respect to LHC Run 2, a reduction of a factor$\approx$5 of the statistical uncertainties is estimated, assuming the increase of luminosity from$\sim$21.6$\mathrm{nb}^{-1}$to$\sim$500$\mathrm{nb}^{-1}$..

These values are obtained from the existing measurements at$\sqrt{s} = 8$TeV using an energy interpolation combined with an extrapolation in rapidity [...] ALICE-PUBLIC-2020-007.- Geneva : CERN, 2020 Fulltext: PDF; 2020-07-31 03:26  Supplemental Material: Measurements of the groomed jet radius and groomed momentum fraction in pp and Pb-Pb collisions at$\sqrt{s_{\rm{NN}}}$= 5.02 TeV /ALICE Collaboration This note presents jet substructure measurements in pp and Pb-Pb collisions at$\sqrt{s_{\rm{NN}}}\$ = 5.02 TeV with the ALICE detector. The Soft Drop grooming algorithm provides access to the hard parton splittings inside a jet by removing soft wide-angle radiation. [...] ALICE-PUBLIC-2020-006.- Geneva : CERN, 2020 - 24. v2: PDF;
