我们给出了Ginsparg-Wilson方程的一个手性解。这项工作的动机是我们最近提出的非微扰调节手性规范理论,其中五维域壁费米子耦合到四维规范场,作为梯度流动方程的解扩展到额外的维度。远表面的镜像费米子与规范场去耦,就好像它们的形状因子随着两个表面之间距离的增加而变得无限柔软。在无限额外维的极限下,我们导出了一个有效的四维手性重叠算子,该算子服从Ginsparg-Wilson方程,并正确地再现了连续统中手性规范理论的一些特性。
We present a chiral solution of the Ginsparg-Wilson equation. This work is motivated by our recent proposal for nonperturbatively regulating chiral gauge theories, where five-dimensional domain wall fermions couple to a four-dimensional gauge field that is extended into the extra dimension as the solution to a gradient flow equation. Mirror fermions at the far surface decouple from the gauge field as if they have form factors that become infinitely soft as the distance between the two surfaces is increased. In the limit of an infinite extra dimension we derive an effective four-dimensional chiral overlap operator which is shown to obey the Ginsparg-Wilson equation, and which correctly reproduces a number of properties expected of chiral gauge theories in the continuum.
