论文摘要
我们采用了连接模型，加上流体动力方程来研究夸克 - 葡萄糖血浆（QGP）中的炭分解和再生，并在$ \ sqrt的能量中具有巨大的Baryon化学潜力，并具有巨大的Baryon化学潜力。 Baryon化学势$μ_b$均在debye质量中编码，这些质量分别表征了夸克电势和整体培养基的状态方程（EOS）。在考虑了重Quarkonium和QGP培养基中的$μ_b$ - 校正之后，我们计算了Charmonium的核修饰因子$ r_ {aa} $。并找到$ \ sqrt {s_ {s_ {nn}} $ = 39和14.5 GEV的$μ_b$对炭的产生的影响，而charmonium的$ r_ {aa} $却忽略不计，考虑$μ_b$的$ r_ {aa} $考虑考虑以$ \ \ sqrt的影响。这对于研究低能量和固定目标重型离子碰撞至关重要。
We employ the transport model coupled with hydrodynamic equations to study the charmonium dissociation and regeneration in the quark-gluon plasma (QGP) with the large baryon chemical potential in Au-Au collisions at the energies of $\sqrt{s_{NN}}=$ ($39$, $14.5$, $7.7$) GeV. The baryon chemical potential $μ_B$ is encoded in both Debye mass characterizing the heavy-quark potential and also the equation of state (EoS) of the bulk medium respectively. After considering $μ_B$-corrections in both heavy quarkonium and the QGP medium, we calculate the nuclear modification factor $R_{AA}$ of charmonium. And find the $μ_B$ influence on charmonium production at $\sqrt{s_{NN}}$ = 39 and 14.5 GeV is negligible, while the $R_{AA}$ of charmonium is reduced considering $μ_B$ influence at $\sqrt{s_{NN}}=7.7$ GeV Au-Au collisions. It is crucial for studying charmonium production in low energy and also fixed-target heavy-ion collisions.
