Abstract:
The transverse momentum distributions of the strange and double-strange hyperon resonances (, ) produced in p-Pb collisions at TeV were measured in the rapidity range for event classes corresponding to different charged-particle multiplicity densities, d/d. The mean transverse momentum values are presented as a function of d/d, 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 d/d. The equivalent ratios to pions exhibit an increase with d/d, depending on their strangeness content.
