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
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.

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. Phys. Inst.) ; Adler, Alexander (Goethe U., Frankfurt, Inst.

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. [...]

Balance functions of (un)identified hadrons in Pb--Pb, p--Pb, and pp collisions at the LHC / Pan, Jinjin (Wayne State U.)
In ultrarelativistic heavy-ion collisions, correlations of particles with opposite quantum numbers provide insight into quark production mechanisms and time scales, collective motion, and re-scattering in the hadronic phase. [...]

Multiplicity dependence of light-flavor hadron production in pp collisions at $\sqrt{s}$ = 7 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Torales - Acosta, Fernando (UC, Berkeley) ; Adamova, Dagmar (Rez, Nucl.

Comprehensive results on the production of unidentified charged particles, $\pi^{+}$, $\rm{K}^{\pm}$, $\rm{K}^{0}_{S}$, K*(892)$^{0}$, $\rm{p}$, $\overline{\rm{p}}$, $\phi$(1020), $\Lambda$, $\overline{\Lambda}$, $\Xi^{-}$, $\overline{\Xi}^{+}$, $\Omega^{-}$ and $\overline{\Omega}^{+}$ hadrons in proton-proton (pp) collisions at $\sqrt{s}$ = 7 TeV at midrapidity ($|y| < 0.5$) as a function of charged-particle multiplicity density are presented. In order to avoid auto-correlation biases, the actual transverse momentum ($p_{\rm{T}}$) spectra of the particles under study and the event activity are measured in different rapidity windows [...]
