Description
The $\rm{f}_{0}$(980) was observed years ago in $\pi\pi$ scattering experiments. Despite a long history of experimental and theoretical research, the nature of such a short-lived resonance is not understood and there is no consensus on its quark content.
The $\rm{f}_{0}$(980) resonance is measured by ALICE using the $\pi\pi$ decay channel. In this contribution, the multiplicity dependence of transverse-momentum spectra and integrated yields of the $\rm{f}_{0}$(980) produced in pp and p--Pb collisions at $\sqrt{s_{\rm{NN}}} =$ 5.02 TeV are presented. These results are compared with theoretical calculations assuming a molecular structure and a compact tetraquark state. In addition, the nuclear modification factor measured in p--Pb collisions is also presented.
