Production of Σ(1385)± and Ξ(1530)0 in p–Pb collisions at √sNN = 5.02 TeV
Abstract
The transverse momentum distributions of the
strange and double-strange hyperon resonances ((1385)±,
(1530)0) produced in p–Pb collisions at √sNN = 5.02
TeV were measured in the rapidity range −0.5 < yCMS < 0
for event classes corresponding to different charged-particle
multiplicity densities, dNch/dηlab . The mean transverse
momentum values are presented as a function ofdNch/dηlab ,
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 . The equivalent ratios to pions
exhibit an increase with dNch/dηlab , depending on their
strangeness content.
