Query: New measures of longitudinal decorrelation of harmonic flow   Harmonic flow in relativistic heavy-ion collisions is observed in a broad
range of rapidities, and the flow at different rapidities is correlated.
However, fluctuations lead to a small decorrelation of the harmonic flow
magnitudes and flow angles at different rapidities. Using a hydrodynamic model
with Glauber Monte Carlo initial conditions we show that the flow angle
decorrelation strongly depends on the flow magnitude in the event. We propose
observables to measure this effect in experiment.
