在夸克味动力学的计算中，除包含ｕ、ｄ、ｓ夸克及其反夸克外，还涉及粲夸克及其反夸克（ｃｃ），采用包含夸克味动力学效应的相对论性流体力学模型，计算了碰撞能量为２００ＧｅＶ／ｕ的２３８Ｕ＋２３８Ｕ核碰撞时形成的膨胀ＱＧＰ及其在相变过程中发射的双轻子谱，轻子对的质量范围Ｍ≤４ＧｅＶ／ｃ２．计算结果与ＣＥＲＮＳＰＳ的实验测量数据进行了定性的比较和分析，得到初步的结论：由于夸克碎块和味动力学效应，Ｊ／ψ→μ＋＋μ－峰值被降低，导致低质量区（阈至１．３５ＧｅＶ／ｃ２）谱的提高．
In addition to u, d, s quarks and their anti-quarks, quark quarks and their antiquarks (cc) are involved in the calculation of quarks’ kinetics, and relativistic hydrodynamic models involving quark flavor dynamics are used to calculate The mass Qq of 238U + 238U with collision energy of 200GeV / u and the double lepton spectrum emitted during the phase transition are shown in the mass range of lepton M≤4GeV / c2. The results of the calculation and the experimental data of CERNSPS are qualitatively compared and analyzed. It is concluded that the J / ψ → μ ++ μ-peak is reduced due to quark fragmentation and taste-kinetic effects, resulting in a low mass region (threshold up to 1). 35GeV / c2) increase in the spectrum.
