摘要
在4、6、8和10.7 AG eV下测量了A - u+ A - u碰撞的快速光谱和K (cid:0)和K +的产率。K (cid:0)产率随束流能量的增加比K +快,因此K (cid:0) /K +比值随束流能量的增加而增加。这个比率被研究为p - s和p - s - p - s的函数,它允许在p+ p反应中直接比较kaon产率与生产阈值。在能量高于阈值时,与在能量低于阈值时观察到的K (cid:0) /K +接近一致的比值相比,等于p s - p s的m (cid:0) /K +比值高于阈值。讨论了用K (cid:0) /K +比值测试致密核物质中kaon性质预测变化的方法。
M id-rapidity spectra and yields ofK (cid:0) and K + have been m easured for A u+ A u collisions at 4, 6,8,and 10.7 AG eV .The K (cid:0) yield increases faster with beam energy than for K + and hence the K (cid:0) /K + ratio increases with beam energy. This ratio is studied as a function ofboth p s and p s - p s th which allowsthedirectcom parison ofthekaon yieldswith respectto theproduction threshold in p+ p reactions.Forequal p s - p s th the m easured ratio K (cid:0) /K + = 0.2 atenergiesabove threshold in contrastto the K (cid:0) /K + ratio ofnearunity observed atenergies below threshold.The use ofthe K (cid:0) /K + ratio to testthe predicted changesofkaon propertiesin dense nuclearm atterisdiscussed.
