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 ... -
The evolution of the near-side peak in two-particle number and transverse momentum correlations in Pb–Pb collisions from ALICE
(Peer reviewed; Journal article, 2019-01-22)Two-particle number and transverse momentum correlations are powerful tools for studying the medium produced in heavy-ion collisions. Correlations in the angular separation of pairs of hadrons can provide information on ... -
Inclusive J/ψ cross section in proton-proton collisions at the center-of-mass energy 13TeV with ALICE

Integration and design for the ALICE ITS readout chain
(Master thesis, 2018-06-26)ALICE and its Inner Tracking System detector in the LHC at CERN will undergo a major upgrade during its second long shutdown taking place in 2019 and 2020. New silicon sensors called ALPIDE will be utilized, which requires ... -
Investigations of anisotropic collectivity using multi-particle correlations in pp, p-Pb and Pb-Pb collisions
(Peer reviewed; Journal article, 2017-11)Two- and multi-particle azimuthal correlations have proven to be an excellent tool to probe the properties of the strongly interacting matter created in heavy-ion collisions. Recently, the results obtained for multi-particle ... -
Jet-hadron correlations relative to the event plane at the LHC with ALICE
(Peer reviewed; Journal article, 2017-11)In ultra relativistic heavy-ion collisions at the Large Hadron Collider (LHC), conditions are met to produce a hot, dense and strongly interacting medium known as the Quark Gluon Plasma (QGP). Quarks and gluons from incoming ... -
Measurement of \(J/\psi\) production as a function of event multiplicity in pp collisions at \(\sqrt{s} = 13\,\mathrm{TeV}\) with ALICE
(Peer reviewed; Journal article, 2017-11)The availability at the LHC of the largest collision energy in pp collisions allows a significant advance in the measurement of \(J/\psi\) production as function of event multiplicity. The interesting relative increase ... -
