超图的改进方法
Improved Methods for Hypergraphs
摘要:
在N=2的超空间中,我们引入了一种新的背景场方法。(We处理射影超空间,但类似的评论也适用于调和情况。)与N=1类似,背景规范场是实表象,所以最低维势是旋量,通常的非重整化定理是明显的。另一个结果是R坐标从有效作用量中消失。
英文摘要:
We introduce a new background field method for N=2 superspace. (We treat projective hyperspace, but similar remarks apply for the harmonic case.) In analogy to N=1, background gauge fields are in the real representation, so the lowest-dimension potentials are spinor and the usual non-renormalization theorems are manifest. Another consequence is that the R-coordinates disappear from the effective action.
