有根交错费米子的有效场论

Effective field theories for rooted staggered fermions

Claude Bernard, Maarten Golterman, Yigal Shamir

摘要:

我们扩展的Symanzik有效行动的建设,包括根交错费米子,从广义的重整化群方法扎根交错费米子。西曼齐克作用量,再加上通常从局部的、部分猝灭的基本理论中构造出的部分猝灭的手征有效理论,就可以用来推导手征有效理论。后者再现扎根交错手征微扰理论。

英文摘要:

We extend the construction of the Symanzik effective action to include rooted staggered fermions, starting from a generalization of the renormalization-group approach to rooted staggered fermions. The Symanzik action, together with the usual construction of a partially quenched chiral effective theory from a local, partially quenched, fundamental theory, can then be used to derive the chiral effective theory. The latter reproduces rooted staggered chiral perturbation theory.
