Addressing the hypertriton lifetime puzzle with ALICE at the LHC
(Journal article; Peer reviewed, 2019)The ALICE Collaboration collected a large data sample of Pb-Pb collisions at in 2015 at the Large Hadron Collider (LHC) and the excellent particle identification (PID) capabilities allow for the detection of rarely produced ... -
ALICE measurement of the J/ψ nuclear modification factor at mid-rapidity in Pb–Pb collisions at √sNN = 5.02 TeV
(Journal article; Peer reviewed, 2017)ALICE at the LHC provides unique capabilities to study charmonium production at low transverse momenta (pT). At central rapidity, (|y| < 0.8), ALICE can reconstruct J/ψ via their decay into two electrons down to zero pT. ... -
ALICE measurements of flow coefficients and their correlations in small (pp and p–Pb) and large (Xe–Xe and Pb–Pb) collision systems
(Journal article; Peer reviewed, 2019)Many observables which are used as a signature of the collective effects in heavy-ion collisions when measured in high multiplicity pp and pA interactions reveal a very similar behaviour. We will present first measurements ... -
ALICE results on system-size dependence of charged-particle multiplicity density in p–Pb, Pb–Pb and Xe–Xe collisions
(Journal article; Peer reviewed, 2019)Particle production at LHC energies involves the interplay of hard (perturbative) and soft (non-perturbative) QCD processes. Global observables, such as the charged-particle multiplicity, are related to the initial geometry ... -
Anisotropic flow of inclusive and identified particles in Pb–Pb collisions at √sNN=5.02 TeV with ALICE

Azimuthally differential pion femtoscopy relative to the second and thrid harmonic in Pb-Pb 2.76 TeV collisions from ALICE
(Journal article; Peer reviewed, 2017)Azimuthally differential femtoscopic measurements, being sensitive to spatio-temporal characteristics of the source as well as to the collective velocity fields at freeze-out, provide very important information on the ... -
Balance functions of (un)identified hadrons in Pb–Pb, p–Pb, and pp collisions at the LHC
(Journal article; Peer reviewed, 2019)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 ... -
Charmonium production in Pb–Pb and p–Pb collisions at forward rapidity measured with ALICE
(Journal article; Peer reviewed, 2017)First experimental results are presented on event-by-event net-proton fluctuation measurements in Pb- Pb collisions at √sNN = 2.76 TeV, recorded by the ALICE detector at the CERN LHC. The ALICE detector is well suited for ... -
Constraining production models with light (anti-)nuclei measurements in small systems with ALICE at the LHC
(Journal article; Peer reviewed, 2019)The production of deuterons and anti-deuterons in pp collisions at has been studied as a function of charged-particle multiplicity using the ALICE detector at the LHC. The preliminary results are shown here, together with ... -
D-meson nuclear modification factor and elliptic flow measurements in Pb–Pb collisions at √sNN=5.02TeV with ALICE at the LHC
