单圈引力自能对量子Wilson圈的贡献

Contributions to Quantum Wilson Loops of the Graviton Self energy

用微扰方法计算了Ｅｉｎｓｔｅｉｎ引力的量子Ｗｉｌｓｏｎ圈带头项贡献，以及单圈引力自能、引力子三顶点对它的修正．结果表明，当考虑单圈引力子自能及引力子三顶点的贡献后，Ｅｉｎｓｔｅｉｎ引力将获得曲率的激发．

The contributions to quantum Wilson loop from the lowest order graviton self energy for Einstein's gravity are calculated perturbatively. The results show that Einstein's gravity will obtain excitations with localized curvature when the graviton self energy is considered.
