| Despite the f0(980) hadron having been discovered half a century ago, the question about its quark content has not been settled: it might be an ordinary quark-antiquark () meson, a tetraquark () exotic state, a kaon-antikaon () molecule, or a quark-antiquark-gluon () hybrid. This paper reports strong evidence that the f0(980) state is an ordinary meson, inferred from the scaling of elliptic anisotropies (v2) with the number of constituent quarks (nq), as empirically established using conventional hadrons in relativistic heavy ion collisions. The f0(980) state is reconstructed via its dominant decay channel f0(980) → π+π−, in proton-lead collisions recorded by the CMS experiment at the LHC, and its v2 is measured as a function of transverse momentum (pT). It is found that the nq = 2 ( state) hypothesis is favored over nq = 4 ( or states) by 7.7, 6.3, or 3.1 standard deviations in the pT < 10, 8, or 6 GeV … |
