THERMAL MODEL INTERPRETATION OF PARTICLE PRODUCTION IN pp INTERACTIONS AROUND s^1/2 ? 10 GeV

merous hadron yields measured in p+p collisions at root s = 8.8, 12.3, and The statistical hadronization model ThermalFist was applied to nu17.3 GeV, including recently published yields of phi and K-S(0)-mesons, measured by the NA61/SHINE Collaboration. We consistently used the energydependent widths of Breit-Wigner mass distributions of hadronic resonances. The canonical treatment of particles with open strangeness combined with the grand canonical approach for non-strange particles gave a moderately reasonable agreement with the measured yields, quantified by chi(2)/NDF approximate to 2-7, only when the volume of strange particles was allowed to vary freely. This volume is found to be greater than the one for non-strange matter for all the studied energies. The predicted yields of some of not yet measured particles are provided.
