在高能时,粒子的运动速度非常快,因此它们的轨迹可以用与它们的速度共线的直线来近似。快胶子沿着直线运动的适当自由度是威尔逊线算符--沿着直线排列的无限规范因子。本文从威尔逊线自由度的角度对高能散射的研究进行了综述。
At high energies the particles move very fast so their trajectories can be approximated by straight lines collinear to their velocities. The proper degrees of freedom for the fast gluons moving along the straight lines are the Wilson-line operators -- infinite gauge factors ordered along the straight line. I review the study of the high-energy scattering in terms of Wilson-line degrees of freedom.
