giant neutron-and hyperon-halos in drip-line nuclei ( meng jie, lv hongfeng, zhang shuangquan et al ) searching for the pentaquark ( lv xiaorui, mao yajun, ma boqiang ) 滴線原子核中的暈現(xiàn)象??中子暈、超子暈、巨暈和形變暈[孟杰,呂洪鳳,張雙全等]
the results show that-condensate appears at some baryon densities and makes great effect to the curve of state equation of neutron star; hyperons-and a exist in neutron star matter at high desities 結(jié)果表明,~-凝聚將出現(xiàn)在一定的重子密度區(qū)間,并對中子星狀態(tài)方程曲線有重要的影響;超子~-和在較高密度也會出現(xiàn)。
the model reproduced the following facts of wa97 experimental data : the yield of strange particles increases with increasing mass and increasing centrality of the colliding system, and also with increasing strangeness content of hyperons in relativis-tic nucleus-nucleus collisions . the simulation of strangeness production using luc1ae model shows that strangeness production is related not only to the rescattering . but also to the collective interaction among strings in relativistic nucleus-nucleus collisions luciae模型能很好地描寫wa97發(fā)表的單奇異和多奇異重子的產(chǎn)額和橫質(zhì)量分布的實驗數(shù)據(jù),能較好描寫wa97實驗所揭示的相對論性核-核碰撞中奇異粒子產(chǎn)額隨碰撞體系質(zhì)量、中心度的增大而增加和奇異粒子增強(qiáng)隨奇異粒子所含奇異夸克數(shù)的增加而增強(qiáng)的實驗事實。
