共形不变性=连续性与Beta变形N=4 SYM理论

Conformal Invariance = Finiteness and Beta Deformed N=4 SYM Theory

D. I. Kazakov, L. V. Bork

摘要:

我们声称,如果通过选择的耦合理论可以共形不变(消失的β函数),它是自动有限的,反之亦然。超对称规范理论的例子证明了这一点。形式主义,然后适用于β变形${\cal N}=4$ SYM理论,它表明,共形不变性=有限性的要求,可以实现任何复杂的变形参数。

英文摘要:

We claim that if by a choice of the couplings the theory can be made conformally invariant (vanishing of the beta functions) it is automatically finite and vice versa. This is demonstrated by explicit example in supersymmetric gauge theory. The formalism is then applied to the beta deformed ${\cal N}=4$ SYM theory and it is shown that the requirement of conformal invariance = finiteness can be achieved for any complex parameter of deformations.
