Portal Matter and Scotogenic-like Dirac Neutrino Masses
Thomas G. Rizzo
Loops of portal matter (PM) fields, carrying both Standard Model (SM) and dark charges, can generate the necessary kinetic mixing (KM) between the ordinary and dark photons (DP) in…
A Model for Dark Moments of the W Boson
Thomas G. Rizzo
Loops of portal matter (PM) fields carrying both dark and Standard Model (SM) quantum numbers can lead to the kinetic mixing (KM) of the SM photon and the analogous dark photon (DP…
Identifying Charged Lepton-like Portal Matter at Future Colliders
Thomas G. Rizzo
In the Kinetic Mixing (KM) portal scenario, the interaction of dark matter (DM) with the particles of the Standard Model (SM) is generated by diagrams connecting the familiar photo…
Portal Matter Models of Kinetic Mixing with Two Light Dark Gauge Bosons
Thomas G. Rizzo
The kinetic mixing (KM) portal mandates the existence of at least one new gauge boson, the dark photon (DP) based on the group , which mixes with the Standard Model (SM) ph…
Towards UV-Models of Kinetic Mixing and Portal Matter VII: A Light Dark Photon in the Model
Thomas G. Rizzo
The kinetic mixing (KM) portal, by which the Standard Model (SM) photon mixes with a light dark photon arising from a new gauge group, allows for the possibility of viable…
Towards UV Models of Kinetic Mixing and Portal Matter: A More Complex Dark Matter Sector?
Thomas G. Rizzo
Portal Matter, with both SM and dark charges, induces KM between the dark photon and the SM gauge fields offering an attractive mechanism by which light thermal DM can obt…
