Stout涂抹2+1味SLiNC费米子的Clover改进：非微扰结果
Clover improvement for stout-smeared 2+1 flavour SLiNC fermions: non-perturbative results
摘要：
我们讨论了一个行动中，费米子矩阵有单级坚固涂抹的跳跃条款与未涂抹的链接三叶草条款。与（树级）西曼齐克改进的胶子作用量，这构成了Stout Link非微扰三叶草或SLiNC作用量。为了消除O（a）项，必须调整三叶草系数csw。我们在这里提出的非微扰确定csw使用薛定谔泛函和作为副产品的临界跳跃参数的测定的初步结果。还给出了局部矢量电流的重整化常数的确定。与最低阶微扰理论的结果进行了比较。
英文摘要：
We discuss an action in which the fermion matrix has single level stout smearing for the hopping terms together with unsmeared links for the clover term. With the (tree level) Symanzik improved gluon action this constitutes the Stout Link Non-perturbative Clover or SLiNC action. To cancel O(a) terms the clover coefficient, csw, has to be tuned. We present here preliminary results of a non-perturbative determination of csw using the Schrodinger functional and as a by-product also a determination of the critical hopping parameter. A determination of the renormalisation constant for the local vector current is also given. Comparisons of the results are made with lowest order perturbation theory results.
