大横动量双轻子极化的最佳自旋量子化轴
Optimal spin-quantization axes for the polarization of dileptons with large transverse momentum
摘要：
产生具有大横向动量的双轻子的首阶部分子过程预测，对于几乎任何选择的虚光子自旋的量子化轴，横向极化都应该随着横向动量的增加而增加。接近完全横向极化的速率取决于自旋量子化轴的选择。我们提出了优化接近速率的轴。它们由双轻子的动量和提供大部分平衡横向动量的喷流的方向决定。
英文摘要：
The leading-order parton processes that produce a dilepton with large transverse momentum predict that the transverse polarization should increase with the transverse momentum for almost any choice of the quantization axis for the spin of the virtual photon. The rate of approach to complete transverse polarization depends on the choice of spin quantization axis. We propose axes that optimize that rate of approach. They are determined by the momentum of the dilepton and the direction of the jet that provides most of the balancing transverse momentum.
