Multiple strange-hadron production yields as a function of the unbiased average charged-particle multiplicity \dndetaNew for \kzero (a), \lmb (b), \XiNosign (c) and \OmNosign (d). Full markers correspond to particles, open markers to antiparticles. Model predictions are reported for \pem, \pecrr and \eplhc as dotted, continuous and dashed lines respectively.
