Elliptic anisotropy measurement of the $\rm{f}_0(980)$ hadron in proton-lead collisions and evidence of its quark-antiquark composition by CMS
Despite its discovery half a century ago, the question about the quark content of the $\rm{f}_0(980)$ hadron has not been settled, whether its being an ordinary quark-antiquark meson, a tetraquark exotic state, a kaon-antikaon molecule, or a quark-antiquark-gluon hybrid. In this note, evidence that...
