A Warped Scalar Portal to Fermionic Dark Matter: A 5D Extension of the Standard Model Linking Visible Matter and the Dark Sector

To the point

Mainz researchers, including Javier Castellano Ruiz and Matthias Neubert, propose that a heavy Higgs-like particle from a five-dimensional extension of the Standard Model mediates a new force between ordinary matter and dark matter, acting as a calculable portal that makes dark matter testable in upcoming experiments even though the mediator is too heavy to be produced at the LHC.

Searching for Dark Matter Through the Fifth Dimension – New Theoretical Physics Discovery to Help Unravel the Mysteries of Dark Matter

A theory involving a fifth dimension may link visible matter with dark matter via a new heavy particle, bringing long-sought experimental tests within reach. Theoretical physicists of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) are working on a theory that goes
