Abstract (data abstract)

The dependence of f$_{0}$(980) production on the final-state charged-particle multiplicity in p-Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 5.02 TeV is reported. The production of f$_{0}$(980) is measured with the ALICE detector via the f$_{0}$(980) $\rightarrow \pi^{+}\pi^{-}$ decay channel in a midrapidity region of $-0.5 < \mathrm{y} < 0$. Particle yield ratios of f$_{0}$(980) to $\pi$ and K$^{*}$(892)$^{0}$ are found to be decreasing with increasing charged-particle multiplicity. The magnitude of the suppression of the f$_{0}$(980)/$\pi$ and f$_{0}$(980)/K$^{*}$(892)$^{0}$ yield ratios is found to be dependent on the transverse momentum $p_\mathrm{T}$, suggesting different mechanisms responsible for the measured effects. Furthermore, the nuclear modification factor $Q_\mathrm{pPb}$ of f$_{0}$(980) is measured in various multiplicity ranges. The $Q_\mathrm{pPb}$ shows a strong suppression of the f$_{0}$(980) production in the $p_\mathrm{T}$ region up to about 4 GeV/$c$ The results on the particle yield ratios and $Q_\mathrm{pPb}$ for f$_{0}$(980) may help to understand the late hadronic phase in p-Pb collisions and the nature of the internal structure of f$_{0}$(980) particle
