K ratio from high-energy heavy-ion collisions Academic Article

abstract

• In an expanding fireball model, we determine the K ratio from heavy-ion collisions at 14.5 GeV/nucleon available from the Brookhaven AGS. Assuming the formation of a quark-gluon plasma in the initial stage, we obtain ratios of 23% and 5% for K+ + and K- -, respectively, which are comparable to the measured values. In the absence of quark-gluon plasma formation, the resulting K- - ratio has about the same value but the K+ + ratio is about a factor of two smaller than the measured value. 1989.
