Balance functions of (un)identified hadrons in Pb--Pb, p--Pb, and pp collisions at the LHC / Pan, Jinjin
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. [...]

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 [...]

Medium modification of the shape of small-radius jets in central Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 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.
We present the measurement of a new set of jet shape observables for track-based jets in central Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV. The set of jet shapes includes the first radial moment or angularity, $g$; the momentum dispersion, $p_{\rm{T}}D$; and the difference between the leading and sub-leading constituent track transverse momentum, $LeSub$.

Measurement of dielectron production in central Pb-Pb collisions at $\sqrt{{\textit{s}}_{\mathrm{NN}}}$ = 2.76 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Torales - Acosta, Fernando (UC, Berkeley) ; Adamova, Dagmar (Rez, Nucl.

The first measurement of dielectron ($\mathrm{e}^{+}\mathrm{e}^{-}$) production in central (0$-$10$\%$) Pb--Pb collisions at a center-of-mass energy per nucleon pair $\mathbf{\sqrt{{\textit{s}}_{\mathrm{NN}}}}$ = 2.76 TeV at the LHC is presented. The dielectron invariant-mass spectrum is measured in the ALICE central barrel detectors for electrons with pseudorapidity $|\eta_{\mathrm{e}}|<0.8$ and transverse momentum $0.4 < p_{\mathrm{T}, \mathrm{e}} < 5$ GeV/$\textit{c}$ [...]
