格手征规范理论中反常的消失

Vanishing of the anomaly in lattice chiral gauge theory

Vieri Mastropietro

摘要:

异常抵消是标准模型的一个基本性质,对标准模型的一致性至关重要。本文考虑四维空间中无质量Wilson费米子与有质量U(1)场相互作用的格手征规范理论。我们证明在无限体积的限制,弱耦合和玻色子质量的顺序的逆晶格步骤,异常消失的subleading修正和在连续相同的条件下。证明是基于精确的重整化群,非微扰的衰变界的相关性和晶格对称性的组合。

英文摘要:

The anomaly cancellation is a basic property of the Standard Model, crucial for its consistence. We consider a lattice chiral gauge theory of massless Wilson fermions interacting with a non-compact massive U(1) field coupled with left and right handed fermions in four dimensions. We prove in the infinite volume limit, for weak coupling and inverse lattice step of the order of boson mass, that the anomaly vanishes up to subleading corrections and under the same condition as in the continuum. The proof is based on a combination of exact Renormalization Group, non perturbative decay bounds of correlations and lattice symmetries.
