The structure of the f_0(980) from system size dependent hadronic resonance ratios in p+p, p+Pb, and Pb+Pb collisions at the LHC
It is shown that the hadronic phase in ultra-relativistic heavy ion collisions can be used to understand the properties of the $f_0(980)$ resonance. In particular it is shown that the centrality dependence of the $f_0(980)/\pi$ and $f_0(980)/\phi$ ratios depends strongly on the $f_0(980)\rightarrow \overline{K}+K$ branching ratio and whether the $f_0(980)$ …
