The mean transverse momentum values are presented as a function of dNch/dηlab\langle{\rm d}N_{\rm{ch}}/{\rm d}\eta_{\rm{lab}}\rangle, as well as a function of the particle masses and compared with previous results on hyperon production. The integrated yield ratios of excited to ground-state hyperons are constant as a function of dNch/dηlab\langle{\rm d}N_{\rm{ch}}/{\rm d}\eta_{\rm{lab}}\rangle. The equivalent ratios to pions exhibit an increase with dNch/dηlab\langle{\rm d}N_{\rm{ch}}/{\rm d}\eta_{\rm{lab}}\rangle, depending on their strangeness content
