First measurement of $\rm \Omega_c^0$ production in pp collisions at $\sqrt{s}=13$ TeV with ALICE / Zhu, Jianhui (CCNU, Wuhan, Inst. Part. Phys. ; Darmstadt, GSI) /ALICE Collaboration
Recent measurements of charm-baryon production in proton--proton (pp) collisions at midrapidity by the ALICE collaboration showed that baryon-to-meson yield ratios are significantly higher than those measured in $\rm e^+e^-$ collisions. The charm baryon-to-meson and charm baryon-to-baryon yield ratios provide unique information on hadronization mechanisms since the contributions from parton distribution function and parton--parton scattering terms cancel in the ratios.

New results on the modification of jet structure in Heavy Ion collisions / Santos, Helena (LIP, Lisbon) /ALICE Collaboration ; ATLAS Collaboration ; CMS Collaboration
These proceedings report recent studies performed by the ALICE, ATLAS and CMS experiments on jet substructure in $pp$ and Pb+Pb collisions at $\sqrt{sNN}$ = 5.02 TeV. The dependence of the modification of the jet shape on the dijet transverse momentum asymmetry is presented. [...]

Investigating the hyperon-nucleon strong interaction with a precision measurement of the hypertriton lifetime in ALICE / Mazzaschi, Francesco (INFN, Turin ; Turin U.) /ALICE Collaboration
The hypertriton is a bound state of a proton, a neutron and a Λ baryon. Studying its internalstructure is crucial to investigate the hyperon–nucleon strong interaction and offers insights intothe inner core of neutron stars, where Λ production is favoured. [...]

Measurements of sub-jet fragmentation with ALICE / Mulligan, James (LBNL, NSD ; UC, Berkeley)
High-energy jets offer rich opportunities to study quantum chromodynamics, from investigating the limits of perturbative calculability to constraining the emergent properties of the quark-gluon plasma (QGP). [...]

Exploring jet fragmentation using two-particle correlations with $\Lambda$ and K$^0_{\rm S}$ / Tarasovičová, Lucia Anna (Munster U.)
Complementary to jet reconstruction, two-particle correlations in $\Delta\eta$ and $\Delta\varphi$ are used to study jets, in particular their particle composition. [...]

The elliptic flow of jet particles at midrapidity ($|\eta|$ < 0.8) is measured for the first time in p--Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV and extended down to lower $\it{p}_{\rm T}$ in Pb--Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV. [...]
