Description
Short-lived resonances are powerful probes to understand the hadronic phase in ultra-relativistic heavy-ion collisions, due to their lifetimes of $\sim$10 fm/c, comparable to the time span between chemical and kinetic freeze-out. The measurements of short-lived resonances in pp collisions provide the baseline for heavy-ion collisions measurement. In this respect, we present the multiplicity dependence of the production of $\rm{f}_{0}$(980) at mid-rapidity $(\mid \rm{y} \mid<0.5)$ in pp collisions at $\sqrt{s}$ = 13 TeV.
The measurement has been performed with ALICE at the LHC and the particles have been reconstructed in the $\rm{f}_{0}(980) \rightarrow \pi^{+}\pi^{-}$ decay channel. The poster will include the description of the signal extraction of other resonances having comparable mass to $\rm{f}_{0}$(980), the study of the combinatorial background, the transverse momentum spectra and the mean transverse momentum. In addition, the multiplicity dependence of the $\rm{f}_{0}$(980) yields will be studied and compared to the dependence of other hadrons, in order to shed light on the $\rm{f}_{0}$(980) quark content.
