Measurements of anisotropic flow at low (p_T < 1.5 GeV/c) and intermediate (1.5 < p_T < 5 GeV/c) transverse momentum from the STAR collaboration are reviewed. While at low p_T an ordering of elliptic flow strength with particle mass is…
We propose several new observables/correlators, based on correlations between two or more subevents separated in pseudorapidity $\eta$, to study the longitudinal flow fluctuations. We show that these observables are sensitive to the…
Various notions of fluctuations exist depending on the way one chooses to measure them. We discuss two extreme cases (continuous measurement versus long inter-measurement times) and we see their relation with entropy production and with…

We constrain proton structure fluctuations at small-$x$ by comparing with the HERA diffractive vector meson production data, and find that large geometric fluctuations in the proton wave function are needed. Hydrodynamical simulations of…
