摘要
用蒙特卡洛重正化群方法讨论了二维随机三角点阵上SU(3)×SU(3)手征模型的β函数行为,得出它的行为与四维SU(3)规范理论模型的β函数相似,但强、弱耦合区的过渡更为平滑,不存在尖锐的小峰,标度区从β=5.8开始.
The β function behavior for SU(3)×SU(3) chiral model on 2-dimensional random triangle lattice has been studied with Monte Carlo renormalization group method. The behavior is similar to that of the 4-dimensional SU(3) gauge theory, but it has a smoother transition from weak to strong coupling regions. There is no nonperturbative peak structure. The asymptotic scaling starts beyond β=5.8.
