Inclusive J/$\psi$ production at mid-rapidity in pp collisions at $\sqrt{s}$ = 5.02 TeV
/ ALICE Collaboration, CERN
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$^{-1}$ .

Study of the $\Lambda$-$\Lambda$ interaction with femtoscopy correlations in pp and p-Pb collisions at the LHC
/ ALICE Collaboration, CERN
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.

Tech., Mumbai ; Enrico Fermi Ctr., Rome) ; Ahammed, Zubayer (Calcutta, VECC) et al.
The ALICE collaboration at the CERN LHC reports novel measurements of jet substructure in pp collisions at $\sqrt{s} = 7$ TeV and central Pb--Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV. Jet substructure of track-based jets is explored via iterative declustering and grooming techniques. [...]

The production of charm jets in proton--proton collisions at a center-of-mass energy of $\sqrt{s}=7$ TeV was measured with the ALICE detector at the CERN Large Hadron Collider. The measurement is based on a data sample corresponding to a total integrated luminosity of $6.23$ ${\rm nb}^{-1}$, collected using a minimum-bias trigger. [...]

This work presents the first experimental observation of the attractive strong interaction between a proton and a multi-strange baryon (hyperon) $\Xi^-$. The result is extracted from two-particle correlations of combined p-$\Xi^{-}$$\oplus$p-$\overline{\Xi}^{+}$ pairs measured in p-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV at the LHC with ALICE.

Measurement of jet radial profiles in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 2.76 TeV

The jet radial structure and particle transverse momentum ($p_{\rm T}$) composition within jets are presented in centrality-selected Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 2.76$ TeV. Track-based jets, which are also called charged jets, were reconstructed with a resolution parameter of $R=0.3$ at midrapidity $|\eta_\mathrm{ch\,jet}|<0.6$ for transverse momenta $p_\mathrm{T,\,ch\,jet}=30$-$120$ GeV/$c$.

Production of muons from heavy-flavour hadron decays in pp collisions at $\sqrt{s}=5.02$ TeV
/ ALICE Collaboration, CERN
Production cross sections of muons from semi-leptonic decays of charm and beauty hadrons were measured at forward rapidity ($2.5<y<4$) in proton-proton (pp) collisions at a centre-of-mass energy $\sqrt{s}=5.02$ TeV with the ALICE detector at the CERN LHC. The results were obtained in an extended transverse momentum interval, $2 < p_{\rm T} < 20$ GeV/$c$, and with an improved precision compared to previous measurements performed in the same rapidity interval at centre-of-mass energies $\sqrt{s} = 2.76$ and 7 TeV.

The cross section of jets reconstructed from charged particles is measured in the transverse momentum range of $5<p_\rm{T}<100\ \rm{GeV}/c$ in pp collisions at the center-of-mass energy of $\sqrt{s} = 5.02\ \rm{TeV}$ with the ALICE detector. The jets are reconstructed using the anti-$k_\rm{T}$ algorithm with resolution parameters $R=0.2$, $0.3$, $0.4$, and $0.6$ in the pseudorapidity range $|\eta|< 0.9-R$. [...]

The coherent photoproduction of J/$\psi$ was measured in ultra-peripheral Pb-Pb collisions at a center-of-mass energy $\sqrt{s_{\mathrm{NN}}}~=~5.02$ TeV with the ALICE detector. The J/$\psi$ is detected via its dimuon decay in the forward rapidity region for events where the hadronic activity is required to be minimal. [...]
