摘要
基于微扰法 ,计算了引力子三点、四点Green函数对Einstein引力的量子Wilson圈的贡献 .结果表明 ,在κ4
The contributions to quantum Wilson loop from the three- and four-point Green functions of the connection fields are calculated perturbatively,on a flat background,in pure Einstein gravity.The results show that Einstein gravity will obtain excitations with localized curvature to κ 4 order.
