本文对三味QCD的有限温度相结构分析进行了改进。研究中采用了Iwasaki规范作用量和O($a$)非微扰改进的Wilson-Clover费米子作用量。我们讨论有限尺寸标度分析,包括混合的磁化和能量的可观测量。初步结果显示的连续极限的临界点使用新生成的数据在Nt= 8,10,包括临界赝标介子质量和临界温度的估计。
We present an update of the finite temperature phase structure analysis for three flavor QCD. In the study the Iwasaki gauge action and non-perturvatively O($a$) improved Wilson-Clover fermion action are employed. We discuss finite size scaling analysis including mixings of magnetization-like and energy-like observables. Preliminary results are shown of the continuum limit of the critical point using newly generated data at Nt=8,10, including estimates of the critical pseudo-scalar meson mass and critical temperature.
