We show that a fluid dynamical scenario, already well tested against identified particle spectra, describes quantitatively the observed mass splitting of the elliptical flow coefficients for pions and protons. This provides a strong argument in favor of the existence of a fluid dynamical expansion in collisions at 5.02 TeV.

Example of a semiperipheral scattering, with 8 Pomerons, showing the transverse plane at space-time rapidity . The positions of the Pomerons are indicated by the black dots. String segments having enough energy to escape (corona) are marked green, the thick red ones constitute the core.
