【摘要】 从完全核阻止的假定出发基于３＋１维ＲＨＥ研究了双轻子谱，并得到结论：如果在极端相对论性原子核碰撞中富重子的夸克－胶子物质真地产生了，那么随着初始重子密度的增加，在不变质量２ｍπ和１ＧｅＶ之间双轻子的产生将会显示出强烈的抑制，而且将有一个反常的峰出现在不变质量０．７５ＧｅＶ附近．这些预言可以在ＣＥＲＮ和Ｂｒｏｏｋｈａｖｅｎ即将开展的实验中得到检验．更多还原

【Abstract】 With the increase of the initial baryon density, the dilepton production in invariant masses between 2mπ and 1GeV is shown to be suppressed and an abnormal peak of the dilepton spectrum appears near the invariant mass0.75GeV if the baryonrich quark-gluon matter has been created in relativistic nucleus-nucleus collisions.These predictions are important for several large-scale experiments at CERN and Brookhaven.更多还原
