Description
The f$_0$(980) meson was observed several years ago in $\pi\pi$ scattering experiments. Despite a long history of experimental and theoretical studies, the nature of this short-lived resonance is far from being understood and there is no agreement about its quark structure. According to different models, it has been associated with $q\bar q$ structures, considered as a tetraquark, or as a $K\bar K$ molecule.
In this talk, the nature of the f$_0$(980) resonance is investigated exploiting the excellent tracking and particle identification of the ALICE experiment to measure the differential spectra and integrated yield of the f$_0$(980) meson produced in pp and p-Pb collisions at an energy of $\sqrt s$ = 5.02 TeV. The new results are discussed in the comparison with models and the properties of other hadrons. The nuclear modification factor shows hints of final-state effects in p-Pb collisions and will be presented and discussed in this perspective.
