Weyl不变性和质量的起源

Weyl Invariance and the Origins of Mass

A. R. Gover, A. Shaukat, A. Waldron

摘要:

通过统一和简单的Weyl不变耦合的尺度和物质场,我们构建理论,统一无质量,大规模和部分无质量的激发。质量与拖拉机Weyl重量,和Breitenlohner-Freedman稳定性界在反德西特金额的现实,这些重量。该方法依赖于拖拉机演算-数学机器允许外尔不变性保持在所有阶段的表现。还考虑了具有任意自旋和质量的高自旋系统与牵引子系统之间的等价性。

英文摘要:

By a uniform and simple Weyl invariant coupling of scale and matter fields, we construct theories that unify massless, massive, and partially massless excitations. Masses are related to tractor Weyl weights, and Breitenlohner-Freedman stability bounds in anti de Sitter amount to reality of these weights. The method relies on tractor calculus -- mathematical machinery allowing Weyl invariance to be kept manifest at all stages. The equivalence between tractor and higher spin systems with arbitrary spins and masses is also considered.
