Journal article • #### Constraining the magnitude of the Chiral Magnetic Effect with Event Shape Engineering in Pb-Pb collisions at$\sqrt{s_{\rm NN}}$= 2.76 TeV ﻿ (Elsevier, 2018-02) In ultrarelativistic heavy-ion collisions, the event-by-event variation of the elliptic flow$v_2$reflects fluctuations in the shape of the initial state of the system. This allows to select events with the same centrality ...
