The production rates and the transverse momentum distribution of strange hadrons at mid-rapidity ($\left|y\right| < 0.5$) are measured in proton-proton collisions at $\sqrt{s}$ = 13 TeV as a function of the charged particle multiplicity, using the ALICE detector at the LHC. It is found that the production rates of $\rm{K}^{0}_{S}$, $\Lambda$, $\Xi$, and $\Omega$ increase with the multiplicity faster than what is reported for inclusive charged particles. [...]

/ALICE
An improved value for the lifetime of the (anti-)hypertriton has been obtained using the data sample of Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}} = $ 5.02 TeV collected by the ALICE experiment at the LHC. The (anti-)hypertriton has been reconstructed via its charged two-body mesonic decay channel and the lifetime has been determined from an exponential fit to the d$N$/d($ct$) spectrum. [...]

/ALICE
The first measurement of the Υ(1S) elliptic flow coefficient (v$_{2}$) is performed at forward rapidity (2.5 < $y$ < 4) in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV with the ALICE detector at the LHC. The results are obtained with the scalar product method and are reported as a function of transverse momentum ($p_{\rm T}$ ) up to 15 GeV/$c$ in the 5-60% centrality interval. [...]

The measurement of the production of prompt D$^{0}$, D$^{+}$, D$^{∗+}$, and D$^{+}_{s}$ mesons in p$-$Pb collisions at the centre-of-mass energy per nucleon pair of $\sqrt{s_{\rm NN}}$ = 5.02 TeV, with an integrated luminosity of 292 ± 11$\mu$b$^{−1}$, are reported. Differential production cross sections are measured at mid-rapidity ($-$0.96< $y_{\rm cms}$ < 0.04) as a function of transverse momentum ($p_{\rm T}$) in the intervals 0 < $p_{\rm T}$ < 36 GeV/$c$for D$^{0}$, 1 < $p_{\rm T}$ < 36 GeV/$c$ for D$^{+}$ and D$^{∗+}$, and 2 < $p_{\rm T}$ < 24 GeV/$c$ for D$^{+}_{s}$ mesons.

The measurement of the deuteron and anti-deuteron production in the rapidity range $-1 < y < 0$ as a function of transverse momentum and event multiplicity in p-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV is presented. (Anti-)deuterons are identified via their specific energy loss $\rm{d}E/\rm{d}x$ and via their time-of-flight. [...]

The study of the strength and behaviour of the antikaon-nucleon ($\rm \overline{K}$N) interaction constitutes one of the key focuses of the strangeness sector in low-energy Quantum Chromodynamics (QCD). In this letter a unique high-precision measurement of the strong interaction between kaons and protons, close and above the kinematic threshold, is presented. [...]

Inclusive J/$\psi$ production is studied in minimum-bias proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 5.02 TeV by ALICE at the CERN LHC. The measurement is performed at mid-rapidity (|y| < 0.9) in the dielectron decay channel down to zero transverse momentum $p_{\rm T}$ , using a data sample corresponding to an integrated luminosity of $L_{int}$ = 19.4 $\pm$ 0.4 nb$^{-1}$ .

This work presents new constraints on the existence and the binding energy of a possible $\Lambda$-$\Lambda$ bound state, the H-dibaryon, derived from $\Lambda$-$\Lambda$ femtoscopic measurements by the ALICE collaboration. The results are obtained from a new measurement using the femtoscopy technique in pp collisions at $\sqrt{s}=13$ TeV and p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV, combined with previously published results from pp collisions at $\sqrt{s}=7$ TeV.

We present a study of the inclusive charged-particle transverse momentum ($p_{\rm T}$) spectra as a function of charged-particle multiplicity density at mid-pseudorapidity, ${\rm d}N_{\rm ch}/{\rm d}\eta$, in pp collisions at $\sqrt{s}=5.02$ and 13 TeV covering the kinematic range $|\eta|<0.8$ and $0.15 < p_{\rm{T}} < 20$ GeV/$c$. The results are presented for events with at least one charged particle in $|\eta|<1$ (INEL$\,>0$). [...]
