Abstract

The dependence of f₀(980) production on the final-state charged-particle multiplicity in p–Pb collisions at s_NN=5.02 TeV is reported. The production of f₀(980) is measured with the ALICE detector via the f₀(980)→π⁺π⁻ decay channel in a midrapidity region of −0.5<y<0. Particle yield ratios of f₀(980) to π and K^⁎(892)⁰ are found to be decreasing with increasing charged-particle multiplicity. The magnitude of the suppression of the f₀(980)/π and f₀(980)/K^⁎(892)⁰ yield ratios is found to be dependent on the transverse momentum p_T, suggesting different mechanisms responsible for the measured effects. Furthermore, the nuclear modification factor Q_pPb of f₀(980) is measured in various multiplicity ranges. The Q_pPb shows a strong suppression of the f₀(980) production in the p_T region up to about 4 GeV/c. The results on the particle yield ratios and Q_pPb for f₀(980) may help to understand the late hadronic phase in p–Pb collisions and the nature of the internal structure of f₀(980) particle.
