  • We have investigated the yield and the spectrum of the K－ mesons in the heavy-ion collisions with the relativistic RBUU approach. It's found that the ratio of the yield of K+ to K－ depends on the size of the nuclear systems. One main reason is caused by the absorption effect of the K－ mesons in the nuclear medium. We have found that the mean-absorption path of the K－ mesons are different for light nuclear system and for the middle or heavy nuclear systems. The extent of the absorption of K－ mesons is different for different elementary production channels. It's one important reason to make the channel Bπ→K－X play an important role in the K－production, especially for light and middle systems.

Abstract: We have investigated the yield and the spectrum of the K－ mesons in the heavy-ion collisions with the relativistic RBUU approach. It's found that the ratio of the yield of K+ to K－ depends on the size of the nuclear systems. One main reason is caused by the absorption effect of the K－ mesons in the nuclear medium. We have found that the mean-absorption path of the K－ mesons are different for light nuclear system and for the middle or heavy nuclear systems. The extent of the absorption of K－ mesons is different for different elementary production channels. It's one important reason to make the channel Bπ→K－X play an important role in the K－production, especially for light and middle systems.
