Observation of abnormal suppression of (980) production in p–Pb collisions at = 5.02 TeV

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 ${f}_{0}\left(980\right)\to {\pi }^{+}{\pi }^{-}$ decay channel in a midrapidity region of $-0.5
