N=4超杨米尔斯中运动夸克辐射的精确公式

An exact formula for the radiation of a moving quark in N=4 super Yang Mills

Diego Correa, Johannes Henn, Juan Maldacena, Amit Sever

摘要:

导出了小角度尖点反常维数的精确公式。这是通过将后者与通过超对称定位执行的某些1/8 BPS威尔逊圈的计算相关联来完成的。这个耦合函数也决定了N=4超杨米尔斯中运动夸克的辐射功率,以及威尔逊圈上位移算符的两点函数的系数。用类似的方法计算了广义尖点反常维数的近BPS展开。

英文摘要:

We derive an exact formula for the cusp anomalous dimension at small angles. This is done by relating the latter to the computation of certain 1/8 BPS Wilson loops which was performed by supersymmetric localization. This function of the coupling also determines the power emitted by a moving quark in N=4 super Yang Mills, as well as the coefficient of the two point function of the displacement operator on the Wilson loop. By a similar method we compute the near BPS expansion of the generalized cusp anomalous dimension.
