Production of $${\Sigma (1385)^{\pm }}$$ and $${\Xi (1530)^{0}}$$Ξ(1530)0 in p–Pb collisions at $${\sqrt{s_{\mathrm{NN}}}= 5.02}$$sNN=5.02 TeV

The transverse momentum distributions of the strange and double-strange hyperon resonances ( $$\Sigma (1385)^{\pm }$$ , $$\Xi (1530)^{0}$$ ) produced in p–Pb collisions at $$\sqrt{s_{\mathrm{NN}}}= 5.02$$ TeV were measured in the rapidity range $$-0.5< y_\mathrm {CMS}<0$$ for event classes corresponding to different charged-particle multiplicity densities, $$\langle $$ d $$N_{\mathrm{ch}}$$ /d $$\eta _{\mathrm{lab}}\rangle $$ . The mean transverse momentum values are presented as a function of $$\langle $$ d $$N_{\mathrm{ch}}$$ /d $$\eta _{\mathrm{lab}}\rangle $$ , 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 $$\langle $$ d $$N_{\mathrm{ch}}$$ /d $$\eta _{\mathrm{lab}}\rangle $$ . The equivalent ratios to pions exhibit an increase with $$\langle $$ d $$N_{\mathrm{ch}}$$ /d $$\eta _{\mathrm{lab}}\rangle $$ , depending on their strangeness content.
