极小加倍费米子及其重整化

Minimally doubled fermions and their renormalization

Stefano Capitani, Michael Creutz, Johannes Weber, Hartmut Wittig

摘要:

最小加倍费米子被提出作为QCD夸克作用量的严格局域离散化,它在有限截止处也保持了手征对称性。我们研究的重整化和混合性质的两个特定的实现的最小加倍费米子在晶格微扰理论在一个循环中,我们构建了保守的轴向电流有一个简单的形式,只涉及最近的邻居网站。我们还介绍了一个符号,它允许一个统一的描述这两个行动的重整化性质。

英文摘要:

Minimally doubled fermions have been proposed as a strictly local discretization of the QCD quark action, which also preserves chiral symmetry at finite cut-off. We study the renormalization and mixing properties of two particular realizations of minimally doubled fermions in lattice perturbation theory at one loop, and we construct conserved axial currents which have a simple form involving only nearest-neighbours sites. We also introduce a notation which allows a unified description of the renormalization properties of both actions.
