Description
Measurements of the distributions of event-by-event flow harmonics $v_n$
and the correlations between harmonics $v_n$ and $v_m$ of different
orders in $\sqrt{s_{NN}}=2.76$ TeV Pb+Pb collisions are presented. These
measurements give insight into the nature of fluctuations in the initial
geometry and the role of linear and non-linear hydrodynamic response to
the fluctuations, the latter can introduce correlations between flow
harmonics. The study of fluctuations is also extended by measurements of
the rapidity dependent fluctuations in the v_n. Furthermore, the
event-by-event fluctuations in the event shape is elucidated by
jet-tomography studies, where the correlations between the $v_n$ of
fully reconstructed jets and the $v_m$ of soft particles are measured.
The latter directly probes the path-length dependent jet quenching
response to the variation of the event-shape controlled by bulk particles.
