无超对称性的二次发散消去

Cancelling Quadratic Divergences Without Supersymmetry

M. T. M. van Kessel

摘要:

我们构建了一个理论,它具有相同的粒子内容作为软破极小超对称QED(MSQED),是免费的二次发散两个循环。这个理论也是完全规范不变的。看来MSQED根本不是唯一没有这些二次发散的理论。这证明了存在非超对称理论,在这些理论中,直到两个圈都不存在二次发散。

英文摘要:

We construct a theory which has the same particle content as softly broken minimal supersymmetric QED (MSQED) and is free of quadratic divergences up to two loops. Also this theory is completely gauge invariant. It appears that MSQED is not at all the only theory without these quadratic divergences. This proves that there exist non supersymmetric theories in which there are no quadratic divergences up to two loops.
