共形重子的反常维数

Anomalous Dimensions of Conformal Baryons

Claudio Pica, Francesco Sannino

摘要:

我们确定了三色理论中重子算符的反常维数,它是微扰理论中已知最大阶数的共形窗口内无质量味数的函数。我们表明,异常尺寸的重子是可控的小,在$δ$ -展开,为一个广泛的数量的味道。我们还发现,这总是小于费米子质量算符的反常维数。这些发现挑战了部分复合性范式。

英文摘要:

We determine the anomalous dimensions of baryon operators for the three color theory as function of the number of massless flavours within the conformal window to the maximum known order in perturbation theory. We show that the anomalous dimension of the baryon is controllably small, within the $δ$-expansion, for a wide range of number of flavours. We also find that this is always smaller than the anomalous dimension of the fermion mass operator. These findings challenge the partial compositeness paradigm.
