We prove the Bisognano–Wichmann property for asymptotically complete Haag–Kastler theories of massless particles. These particles should either be scalar or appear as a direct sum of two opposite integer helicities, thus, e.g., photons are covered. The argument relies on a modularity condition formulated recently by one of us (VM) and on the Buchholz’ scattering theory of massless particles.

渐近完全无质量 QFT 的 Bisognano-Wichmann 性质

我们证明了无质量粒子的渐近完备 Haag-Kastler 理论的 Bisognano-Wichmann 性质。这些粒子要么是标量的，要么表现为两个相反的整数螺旋度的直接和，因此，例如，光子被覆盖。该论点依赖于我们中的一个人（VM）最近制定的模块化条件和无质量粒子的 Buchholz 散射理论。
