Weyl Symmetry Inspired Inflation and Dark Matter

Understand

Motivated by the Weyl scaling gauge symmetry, we present a theoretical framework to explain cosmic inflation and dark matter simultaneously.

• This symmetry has been resurrected in recent attempts to formulate the gauge theory of gravity.
• We show the inspired inflation model is well consistent with current observations and will be probed further by future experiments.
• Furthermore, we clarify and prove the stability of Weyl gauge boson in the general theory with multiple scalars.
