ALICE measured the nuclear modification factor (RAA) and elliptic flow (v2) of D mesons (D0, D+, D∗+ and D+s ) insemi-central Pb–Pb collisions at √sNN = 5.02 TeV. The increased amount of data in semi-central Pb–Pb events ...

(Journal article; Peer reviewed, 2017)
W and Z bosons are massive weakly-interacting particles, insensitive to the strong interaction. They provide therefore a medium-blind probe of the initial state of the heavy-ion collisions. The final results for the W and ...
