论文摘要
已经实施了一种新的蒙特卡洛方法来描述各向异性液体（如水和线性烷基苯甲）的角度和极化分布，通过考虑极化性张量的定向波动。各向异性液体的散射光被去极化，角度分布为$ 1+（1-ρ_V）/（1+3ρ_V）\ cos^2θ$，通过去极化比率$ρ_v$进行了修改。独立的实验验证了实验室的仿真结果。新方法可以在大型液体探测器中提供更准确的知识，这对检测器的重建是有益的。
A new Monte Carlo method has been implemented to describe the angular and polarization distributions of anisotropic liquids, like water and linear alkylbenzene, by considering orientational fluctuations of polarizability tensors. The scattered light of anisotropic liquids is depolarized with an angular distribution of $1+(1-ρ_v)/(1+3ρ_v)\cos^2θ$, which is modified by the depolarization ratio $ρ_v$. A standalone experiment has validated the simulation results of LAB. The new method can provide more accurate knowledge on light propagation in large liquid detectors, which is beneficial to the developments of reconstruction for detectors.
