单尖点威尔逊圈曲面的共形SO(2,4)变换

Conformal SO(2,4) Transformations of the One-Cusp Wilson Loop Surface

Shijong Ryang

摘要:

通过对初等单尖威尔逊圈曲面进行保角SO(2,4)变换,我们在AdS_5中构造了各种双尖和四尖威尔逊圈曲面构型,并证明了它们解Nambu-Goto弦作用量的弦方程。将基本的四尖威尔逊圈曲面与正方形投影共形提升,生成了各种四尖威尔逊圈曲面,它们分别与重标正方形、菱形和菱形投影,并在这些曲面上计算了经典的欧氏Nambu-Goto弦作用量在IR维正则化中的作用量.

英文摘要:

By applying the conformal SO(2,4) transformations to the elementary one-cusp Wilson loop surface we construct various two-cusp and four-cusp Wilson loop surface configurations in AdS_5 and demonstrate that they solve the string equations of the Nambu-Goto string action. The conformal boosts of the basic four-cusp Wilson loop surface with a square-form projection generate various four-cusp Wilson loop surfaces with projections of the rescaled square, the rhombus and the trapezium, on which surfaces the classical Euclidean Nambu-Goto string actions in the IR dimensional regularization are evaluated.
