Weyl geometric gravity and "breaking" of electroweak symmetry

Understand

A Weyl geometric scale covariant approach to gravity due to Omote, Dirac, and Utiyama (1971ff) is reconsidered.

• It can be extended to the electroweak sector of elementary particle fields, taking into account their basic scaling freedom.
• Already Cheng (1988) indicated that electroweak symmetry breaking, usually attributed to the Higgs field with a boson expected at $0.1 - 0.3 \,TeV$, may be due to a coupling between Weyl geometric gravity and electroweak interactions.
• Weyl geometry seems to be well suited for treating questions of elementary particle physics, which relate to scale invariance and its "breaking".
