Observation of abnormal suppression of f0(980) production in p-Pb collisions at root sNN=5.02 TeV

Popis výsledku v původním jazyce

The dependence of f(0)(980) production on the final-state charged-particle multiplicity in p-Pb collisions at root s(NN) = 5.02 TeV is reported. The production of f(0)(980) is measured with the ALICE detector via the f(0)(980) -> pi(+)pi(-) decay channel in a midrapidity region of -0.5 < 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(T), suggesting different mechanisms responsible for the measured effects. Furthermore, the nuclear modification factor Q(pPb) of f(0)(980) is measured in various multiplicity ranges. The Q(pPb) shows a strong suppression of the f(0)(980) production in the p(T) region up to about 4 GeV/c. The results on the particle yield ratios and Q(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.
