In particular, the Einstein-frame … Web10 de jun. de 2024 · In the case of the original Higgs inflation with a large non-minimal coupling, the unitarity problem occurs due to the would-be Goldstone components of the Higgs field [9], [10], [11], [12], which motivated sigma …
Web30 de dez. de 2015 · We investigate an inflationary model involving a gauge singlet scalar and fermionic dark matter. The mixing between the singlet scalar and the Higgs boson provides a portal to dark matter. The inflaton could either be the Higgs boson or the singlet scalar, and slow roll inflation is realized via its non-minimal coupling to gravity. In this …
