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 momentumvalues are presented as a function of dNch/dηlab , as well as a function of the particle masses and compared with previous results on hyperon production. The in ...
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 momentumvalues are presented as a function of dNch/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. ...
