R_3 x S_1上的多味QCD *:研究从阿贝尔到非阿贝尔禁闭的转变

Multiflavor QCD* on R_3 x S_1: Studying Transition From Abelian to Non-Abelian Confinement

M. Shifman, M. Unsal

摘要:

与Seiberg-Witten理论一样,在R_3 × S_1上建立的中心稳定的多味QCD* 理论也表现出阿贝尔禁闭和非阿贝尔禁闭随S_1半径的变化。对于足够少的味数和小的r(S_1),我们证明了在规范涨落中存在质量隙和线性禁闭。这是一种没有连续手征对称性破缺(χSB)的限制状态。与r(S_1)中没有相变的单味理论不同,多味理论具有与连续手征对称性破缺相关的单一相变。我们推测χSB的尺度与阿贝尔到非阿贝尔禁闭跃迁的尺度参数化地联系在一起。

英文摘要:

The center-stabilized multiflavor QCD* theories formulated on R_3 x S_1 exhibit both Abelian and non-Abelian confinement as a function of the S_1 radius, similar to the Seiberg-Witten theory as a function of the mass deformation parameter. For sufficiently small number of flavors and small r(S_1), we show occurence of a mass gap in gauge fluctuations, and linear confinement. This is a regime of confinement without continuous chiral symmetry breaking (χSB). Unlike one-flavor theories where there is no phase transition in r(S_1), the multiflavor theories possess a single phase transition associated with breaking of the continuous chiral symmetry. We conjecture that the scale of the χSB is parametrically tied up with the scale of Abelian to non-Abelian confinement transition.
