The first measurement of longitudinal decorrelations of harmonic flow amplitudes v n for n ¼ 2 – 4 in Xe þ Xe collisions at ffiffiffiffiffiffiffiffi s NN p ¼ 5 . 44 TeV is obtained using 3 μ b − 1 of data with the ATLAS detector at the LHC. The decorrelation signal for v 3 and v 4 is found to be nearly independent of collision centrality and transverse momentum ( p T ) requirements on final-state particles, but for v 2 a strong centrality and p T dependence is seen. When compared with the results from Pb þ Pb…

Longitudinal eccentricity decorrelations in heavy-ion collisions
In heavy-ion collisions, the harmonic flow $V_n$ of final-state particles are driven by the eccentricity vector ${\mathcal{E}}_n$ that describe the shape of the initial fireball projected in the
