Standard Model with Cosmologically Broken Quantum Scale Invariance

Understand

We argue that scale invariance is not anomalous in quantum field theory, provided it is broken cosmologically.

• We consider a locally scale invariant extension of the Standard Model of particle physics and argue that it fits both the particle and cosmological observations.
• The model is scale invariant both classically and quantum mechanically.
• The scale invariance is broken cosmologically producing all the dimensionful parameters.
