Yang-Mills理论在分数时空维度中是否具有幺正性?

Is Yang-Mills Theory Unitary in Fractional Spacetime Dimensions?

Qingjun Jin, Ke Ren, Gang Yang, Rui Yu

AI总结:

研究Yang-Mills理论在非整数时空维度中的幺正性问题,指出瞬逝算子会引发负范数态与复反常维数,从而破坏幺正性。

摘要:

我们给出具体证据,表明Yang-Mills理论在非整数时空维度中表现出非幺正性。这种幺正性破坏源于瞬逝算子:它们在四维中为零,但在一般d维中非零。我们证明,这些瞬逝算子导致负范数态和复反常维数同时出现。

英文摘要:

We present concrete evidence that Yang-Mills theory exhibits non-unitarity in non-integer spacetime dimensions. This violation of unitarity stems from evanescent operators that, while vanishing in four dimensions, are non-zero in general d dimensions. We demonstrate that these evanescent operators lead to the emergence of both negative-norm states and complex anomalous dimensions.
