论文摘要
在使用威尔逊费米斯(Wilson Fermions)2+1个口味的QCD模拟中,通常假定费米昂决定因素的阳性。我们提供证据表明,这一假设一般不合理,并讨论了这一发现的后果。
In the simulation of QCD with 2+1 flavors of Wilson fermions, the positivity of the fermion determinant is generally assumed. We present evidence that this assumption is in general not justified and discuss the consequences of this finding.
