Non-metric geometry as the origin of mass in gauge theories of scale invariance
Abstract We discuss gauge theories of scale invariance beyond the Standard Model (SM) and Einstein gravity. A consequence of gauging this symmetry is that their underlying 4D geometry is non-metric ( $$\nabla _\mu g_{\alpha \beta }\!\not =\!0$$ ∇ μ g α β ≠ 0 ). Examples of such theories are Weyl’s o...
