Addressing the hypertriton lifetime puzzle with ALICE at the LHC
(Peer reviewed; Journal article, 2019)The ALICE Collaboration collected a large data sample of Pb-Pb collisions at√sNN=5.02 TeV in 2015 at the LargeHadron Collider (LHC) and the excellent particle identification (PID) capabilities allow for the detection of ... -
ALICE measurement of the \(J/\psi\) nuclear modification factor at mid-rapidity in Pb–Pb collisions at \(\sqrt{{s}_{NN}}=\) 5.02 TeV
(Peer reviewed; Journal article, 2017-11)ALICE at the LHC provides unique capabilities to study charmonium production at low transverse momenta ( p T ). At central rapidity, ( |y|<0.8 ), ALICE can reconstruct J/ ψ via their decay into two electrons down to zero ... -
ALICE measurements of flow coefficients and their correlations in small (pp and p–Pb) and large (Xe–Xe and Pb–Pb) collision systems
(Peer reviewed; Journal article, 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
(Peer reviewed; Journal article, 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 \(\sqrt{{s}_{NN}}=\) 5.02 TeV with ALICE
(Peer reviewed; Journal article, 2017-11)Anisotropic flow measurements constrain the shear \((\eta/s)\) and bulk \(\zeta/s\) viscosity of the quark-gluon plasma created in heavy-ion collisions, as well as give insight into the initial state of such collisions ... -
Azimuthally differential pion femtoscopy relative to the second and thrid harmonic in Pb-Pb 2.76 TeV collisions from ALICE
(Peer reviewed; Journal article, 2017-11)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
(Peer reviewed; Journal article, 2019-02)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
(Peer reviewed; Journal article, 2017-11)The ALICE collaboration has measured the inclusive charmonium production at forward rapidity in Pb–Pb and p–Pb collisions at sNN=5.02TeV and sNN=8.16TeV , respectively. In Pb–Pb collisions, the J/ ψ and ψ (2S) nuclear ... -
Constraining production models with light (anti-)nuclei measurements in small systems with ALICE at the LHC
(Peer reviewed; Journal article, 2019)The production of deuterons and anti-deuterons in pp collisions at √s = 7 and 13 TeV has been studied as a function of charged-particle multiplicity using the ALICE detector at the LHC. The preliminary results are shown ... -
