Production of the K * (892) 0 and K * (892) 0 resonances was studied via their K + π − and K − π + decay modes in central Pb + Pb, Si + Si, C + C, and inelastic p + p collisions at 158A GeV(√ s NN = 17.3 GeV) with the NA49 detector at the CERN SPS. Transverse momentum and rapidity distributions were measured and total yields were estimated. The yield of K * exceeds that of K * by about a factor of two in nucleus-nucleus reactions. The total yield ratios K * /K + and K * /K − are strongly suppressed in central Pb + Pb compared to p + p, C + C, and Si + Si collisions, in agreement with the expected attenuation of these short-lived resonance states in the hadronic phase of the expanding fireball. The UrQMD model, although incorporating such a scenario, does not provide a quantitative description of the experimental results. The statistical hadron gas model assuming the same freeze-out parameters for stable hadrons and resonances overestimates the K * /K ratios in central Pb + Pb collisions by about a factor of 2.5. |
