论文摘要
已经研究了热QCD培养基中的碰撞过程对$ q \ Overline {q} $ nihihation n nihihitation在相对论重型离子碰撞中的影响。在整体平均扩散的Vlasov-Boltzmann方程的框架内估计了对动量分布函数的非平衡校正，编码了该介质中碰撞过程和湍流的铬田的影响。 $ 2 \ rightArrow2 $弹性散射过程的贡献已被量化用于热Dilepton的生产率。可以看出，碰撞校正以高$ p_t $增强了平衡DILEPTON光谱，并以较低的$ P_T $抑制。还探讨了对DILEPTON生产率的碰撞和异常贡献之间的比较研究。由于无碰撞的异常运输，碰撞的碰撞被认为是微不足道的。
The effects of collisional processes in the hot QCD medium to thermal dilepton production from $q\overline{q}$ annihilation in relativistic heavy-ion collisions have been investigated. The non-equilibrium corrections to the momentum distribution function have been estimated within the framework of ensemble-averaged diffusive Vlasov-Boltzmann equation, encoding the effects of collisional processes and turbulent chromo-fields in the medium. The contributions from the $2\rightarrow2$ elastic scattering processes have been quantified for the thermal dilepton production rate. It is seen that the collisional corrections enhance the equilibrium dilepton spectra at high $p_T$ and suppress at lower $p_T$. A comparative study between collisional and anomalous contributions to the dilepton production rates has also been explored. The collisional contributions are seen to be marginal over that due to collisionless anomalous transport.
