Systematic Study of the Kaon to Pion Multiplicity Ratios in Heavy-Ion Collisions
F. Wang, H. Liu, H. Sorge +2
We present a systematic study of the kaon to pion multiplicity ratios (K+/pi+ and K-/pi-) in heavy-ion collisions from AGS to RHIC energy using the Relativistic Quantum Molecular D…

J. Schaffner-Bielich, R. Mattiello, H. Sorge
Weak SU(3) symmetry is successfully applied to the weak hadronic decay amplitudes of octet hyperons. Weak nonmesonic and mesonic decays of various dibaryons with strangeness, their…
