The second ($v_2$) and third ($v_3$) flow harmonic coefficients of J/$\psi$ mesons are measured at forward rapidity (2.5 $<$ y $<$ 4.0) in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV with the ALICE detector at the LHC. Results are obtained with the scalar product method and reported as a function of transverse momentum, $p_{\rm{T}}$, for various collision centralities. [...]

Charged-particle pseudorapidity density at mid-rapidity in p-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 8.16 TeV / ALICE Collaboration, CERN
The pseudorapidity density of charged particles, $\rm{d}N_\rm{ch}/\rm{d}\eta$, in p-Pb collisions has been measured at a centre-of-mass energy per nucleon-nucleon pair of $\sqrt{s_{\rm{NN}}}$ = 8.16 TeV at mid-pseudorapidity for non-single-diffractive events. The results cover 3.6 units of pseudorapidity, $|\eta|<1.8$. [...]

Jet fragmentation transverse momentum measurements from di-hadron correlations in $\sqrt{s}$ = 7 TeV pp and $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV p-Pb collisions / Acharya, Shreyasi (Calcutta, VECC) ; Torales - Acosta, Fernando (UC, Berkeley) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adhya, Souvik Priyam (Calcutta, VECC) ; Adler, Alexander (Goethe U., Frankfurt, Inst.

The transverse structure of jets was studied via jet fragmentation transverse momentum ($j_{\rm{T}}$) distributions, obtained using two-particle correlations in proton-proton and proton-lead collisions, measured with the ALICE experiment at the LHC. The highest transverse momentum particle in each event is used as the trigger particle and the region 3 < $p_{\rm{Tt}}$ < 15 GeV/$c$ is explored in this study. [...]

Production, spectroscopy and properties of heavy hadrons / Galanti, Mario (Rochester U.) /ALICE,ATLAS,CMS and LHCB Collaborations
In this report I will describe the latest results of the ALICE, ATLAS, CMS, and LHCb experiments in the fields of production, spectroscopy, and properties of heavy hadrons. In particular, I will concentrate on measurements of quarkonium production cross sections, polarization, and mass, on measurements of production cross sections and lifetimes of open heavy flavors, on the recent observations of new states and decay modes, and on other searches for new and exotic hadrons..

$\Lambda_{\rm c}^{+}$ production in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV / Acharya, Shreyasi (Calcutta, VECC) ; Torales - Acosta, Fernando (UC, Berkeley) ; Adamova, Dagmar (Rez, Nucl.

Tech., Mumbai) et al.
A measurement of the production of prompt $\Lambda_{\rm c}^{+}$ baryons in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV with the ALICE detector at the LHC is reported. The $\Lambda_{\rm c}^{+}$ and ${\overline{\Lambda_{\rm c}^{-}}}$ were reconstructed at midrapidity ($|y|<0.5$) via the hadronic decay channel $\Lambda_{\rm c}^{+}\rightarrow {\rm K}_{\rm S}^{0}$ (and charge conjugate) in the transverse momentum and centrality intervals $6<p_{\rm T}<12$ GeV/$c$ and 0–80%.

Event-shape engineering for the D-meson elliptic flow in mid-central Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV / Acharya, Shreyasi (Calcutta, VECC) ; Torales - Acosta, Fernando (UC, Berkeley) ; Adamova, Dagmar (Rez, Nucl.

Tech., Mumbai) ; Ahammed, Zubayer (Calcutta, VECC) et al. /ALICE
The production yield of prompt D mesons and their elliptic flow coefficient $v_2$ were measured with the Event-Shape Engineering (ESE) technique applied to mid-central (10–30% and 30–50% centrality classes) Pb-Pb collisions at the centre-of-mass energy per nucleon pair $\sqrt{s_{\rm NN}}=5.02$ TeV, with the ALICE detector at the LHC. The ESE technique allows the classification of events, belonging to the same centrality, according to the azimuthal anisotropy of soft particle production in the collision. [...]
