Latest flow results and new developments in the flow analyses techniques — •Ante Bilandzic for the ALICE collaboration — Technical University of Munich, Germany

With the advent of large statistics heavy-ion datasets at RHIC and LHC, comprising particularly events with the very large number of produced particles, it is becoming feasible to study the properties of Quark-Gluon Plasma with unprecedented precision. One of the most informative probes in such studies is the collective anisotropic flow, which can be measured very reliably with multiparticle correlation techniques in an environment characterized with large multiplicities and large values of flow harmonics.

In this group report we present an overview of latest flow results, which include: First ALICE results for the recently developed flow observables dubbed higher order Symmetric Cumulants, new analysis technique for the measurement of symmetry plane correlations, development of new hydro-based model to explain ``flow-like'' signals in pp collisions, study of universal non-flow scaling in azimuthal correlators, feasibility study for the usage of multiparticle correlations in flow analyses at CBM experiment, and finally, update on the status of applying multiparticle correlations in femtoscopy.
