Higgs-field Portal into Hidden Sectors
Brian Patt, Frank Wilczek
TL;DR
This paper explores how the Higgs field can act as a portal to hidden sectors, potentially leading to multiple Higgs resonances or invisible decay channels, with implications for particle physics beyond the standard model.
Contribution
It introduces models where singlet fields couple to the Higgs, providing natural examples and discussing phenomenological consequences such as altered Higgs decay modes.
Findings
Higgs portal can induce multiple weaker Higgs resonances
Potential for additional invisible decay channels of the Higgs
Models are consistent and not unnatural within the standard framework
Abstract
The Higgs field mass term, being superrenomalizable, has a unique status within the standard model. Through the opening it affords, singlet fields can have renormalizable couplings to standard model fields. We present examples that are neither grotesque nor unnatural. A possible consequence is to spread the Higgs particle resonance into several weaker ones, or to afford it additional, effectively invisible decay channels.
