单极凝聚的手征对称性破缺

Chiral Symmetry Breaking by Monopole Condensation

Aiichi Iwazaki

摘要:

在QCD中阿贝尔占优的假设下,我们证明了当低能无质量夸克与QCD碰撞时,夸克的色荷和手征都不守恒。因为色荷在现实中是守恒的,所以手征性不守恒。我们利用手征反常证明了当经典色荷在无凝聚的真空中有凝聚时,手征非对称夸克对产生,而手征对称夸克对产生发生在无凝聚的真空中.结果表明,该体系的手征对称性被缩合物破缺。

英文摘要:

Under the assumption of Abelian dominance in QCD, we show that either color charge or chirality of quark is not conserved, when the low energy massless quark collides with QCD monopole. Because the color charge is conserved in reality, the chirality is not conserved. We show by using chiral anomaly that chiral non symmetric quark pair production takes place when a classical color charge is putted in a vacuum with monopole condensation, while chiral symmetric pair production takes place in a vacuum with no monopole condensation. Our results indicate that the chiral symmetry is broken by the monopole condensation.
