Tiivistelmä
The measurements of the (anti)deuteron elliptic flow (v(2)) and the first measurements of triangular flow (v(3)) in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon collision root √sNN = 5.02 TeV are presented. A mass ordering at low transverse momentum (p(T)) is observed when comparing these measurements with those of other identified hadrons, as expected from relativistic hydrodynamics. The measured (anti)deuteron v(2) lies between the predictions from the simple coalescence and blast-wave models, which provide a good description of the data only for more peripheral and for more central collisions, respectively. The mass number scaling, which is violated for v(2), is approximately valid for the (anti)deuterons v(3). The measured v(2) and v(3) are also compared with the predictions from a coalescence approach with phase-space distributions of nucleons generated by IEBE-VISHNU with AMPT initial conditions coupled with URQMD, and from a dynamical model based on relativistic hydrodynamics coupled to the hadronic afterburner SMASH. The model predictions are consistent with the data within the uncertainties in midcentral collisions, while a deviation is observed in the most central collisions.
