$\Lambda_{\rm c}^{+}$ 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. [...]

Production of pions, kaons and protons in Xe--Xe collisions at $\mathbf{\sqrt{{\textit s}_{\mathbf{\rm \mathbf{NN}}}}=5.44} \text{ TeV}$ / Ragoni, Simone (Bologna U. ; INFN, Bologna)
In late 2017, the ALICE experiment recorded a data sample of Xe--Xe collisions at the unprecedented energy in A--A systems of $\sqrt{s_{\rm{NN}}} = 5.44\text{ TeV}$. [...]

Energy dependence of exclusive $J/\psi$ photoproduction off protons in ultra-peripheral p-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Torales - Acosta, Fernando (UC, Berkeley) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst. Inform.) ; Adolfsson, Jonatan (Lund U.) ; Aggarwal, Madan Mohan (Panjab U.) ; Aglieri Rinella, Gianluca (CERN) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Indian Inst. Tech., Mumbai) ; Ahammed, Zubayer (Calcutta, VECC) et al. /ALICE
The ALICE Collaboration has measured the energy dependence of exclusive photoproduction of $J/\psi$ vector mesons off proton targets in ultra–peripheral p-Pb collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV. The $e^{+}e^{-}$ and $\mu^{+}\mu^{-}$ decay channels are used to measure the cross section as a function of the rapidity of the $J/\psi$ in the range −2.5 < $y$ < 2.7, corresponding to an energy in the $\gamma p$ centre-of-mass in the interval 40 < $W_{\gamma p}$ < 550 GeV.

Charged jet cross section and fragmentation in proton-proton collisions at $\sqrt{s}$ = 7 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Torales - Acosta, Fernando (UC, Berkeley) ; Adamova, Dagmar (Rez, Nucl.

We report the differential charged jet cross section and jet fragmentation distributions measured with the ALICE detector in proton-proton collisions at a centre-of-mass energy $\sqrt{s}$ = 7 TeV. Jets with pseudo-rapidity $|\eta|<0.5$ are reconstructed from charged particles using the anti-$k_{T}$ jet finding algorithm with a resolution parameter $R$ = 0.4. [...]

Measuring $\rm{K}^{0}\rm{K}^{\pm}$ interactions using pp collisions at $\sqrt{s}$ = 7 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Torales - Acosta, Fernando (UC, Berkeley) ; Adamova, Dagmar (Rez, Nucl.

We present the first measurements of femtoscopic correlations between the $\rm{K}^{0}$ and $\rm{K}^{\pm}$ particles in pp collisions at $\sqrt{s}$ = 7 TeV measured by the ALICE experiment. The observed femtoscopic correlations are consistent with final-state interactions proceeding solely via the $a_{0}(980)$ resonance. [...]
