+ | R1,3 depend only on the Lie algebra of the gauge group and are unaffected by global | ||
+ | issues such as the choice of Γ. This means that no current experiment can distinguish | ||
+ | between the four possibilities. Nonetheless, the physics in flat space can depend in | ||
+ | subtle ways on Γ (and in more dramatic ways when spacetime has interesting topology). | ||
+ | The purpose of this paper is to describe the crudest differences between the theories: | ||
+ | the spectrum of line operators and the periodicities of theta angles.<cite>https://arxiv.org/pdf/1705.01853.pdf</cite></blockquote> | ||
