标题： Why the overlap formula does not lead to chiral fermions

摘要： 我们描述了一个概念上简单但重要的测试，用于重叠方法在构建格点手征规范理论中的应用。 我们解释了重叠公式与某种波导模型对于一组简单的规范配置（平凡轨道）的等价性。 这种等价性有助于进行测试，并对重叠方法的可行性提出了严重质疑。 Narayanan 和 Neuberger 最近的一篇笔记指出了我们之前工作中的一项错误，在此背景下是不相关的。 显示英文摘要

摘要： We describe a conceptually simple, but important test for the overlap approach to the construction of lattice chiral gauge theories. We explain the equivalence of the overlap formula with a certain waveguide model for a simple set of gauge configurations (the trivial orbit). This equivalence is helpful in carrying out the test, and casts serious doubts on the viability of the overlap approach. A recent note by Narayanan and Neuberger which points out a mistake in our previous work is irrelevant in this context.
