摘要: 我们对SU(2)群格点规范理论的Sinl-Sin((1/2)TrUp)作用量做了有限温度下的Monte Carlo计算,观察到一个高温下解除禁闭的相变。临界点是Tc≈334±40Mev,这与使用Wilson作用量及其它类型作用量所得结果可以相容。

Abstract: Using Monte Carlo techniques we study the SU(2) lattice gauge theory with Sin 1-Sin(TrUp/2) action at finite temperatures.A deconfinement transition at high temperature is observed. The critical point is Tc=334±40Mev, which is consistent with that obtained by using Wilson's action and others.
