Violation of the elliptic flow scaling of

Abstract: We investigate the production and elliptic flow of the f0(980) in high-multiplicity p–Pb collisions at √sNN = 5.02 TeV using a hadronic coalescence model with the K and K̅ phase-space distributions provided by the Hydro–Coal–Frag hybrid model. Our results, which agree with the ALICE and CMS measurements, support the KK̅ molecular interpretation of the f0(980) structure and show, however, a breakdown of the simple number-of-constituent (NC) scaling of its elliptic flow. The latter is in contrast to the deuteron elliptic flow, which exhibits a significantly better NC scaling when the same coalescence width parameter is used.
