Higgs inflation in Weyl-invariant Einstein-Cartan gravity
Georgios K. Karananas, Mikhail Shaposhnikov
Abstract
In this short note we analyze the inflationary dynamics in Weyl-invariant Einstein-Cartan gravity coupled to the Standard Model of particle physics. We take the axion-like particle of gravitational origin to be approximately massless in the early Universe and show how inflation with the Higgs field materializes.
