Forbidden Dark Matter Annihilations into Standard Model Particles
Raffaele Tito D'Agnolo, Di Liu, Joshua T. Ruderman +1
We present kinematically forbidden dark matter annihilations into Standard Model leptons. This mechanism precisely selects the dark matter mass that gives the observed relic abunda…
Edges and Endpoints in 21-cm Observations from Resonant Photon Production
Andrea Caputo, Hongwan Liu, Siddharth Mishra-Sharma +3
We introduce a novel class of signatures---spectral edges and endpoints---in 21-cm measurements resulting from interactions between the standard and dark sectors. Within the contex…
CKM Substructure
Yuval Grossman, Joshua T. Ruderman
The CKM matrix is not generic. The Wolfenstein parametrization encodes structure by having one small parameter, . We pose the question: is there substructure in the…
Dark Higgs Dark Matter
Cristina Mondino, Maxim Pospelov, Joshua T. Ruderman +1
A new dark gauge group coupled to the Standard Model (SM) via the kinetic mixing portal provides a natural dark matter candidate in the form of the Higgs field, , respo…
Modeling Dark Photon Oscillations in Our Inhomogeneous Universe
Andrea Caputo, Hongwan Liu, Siddharth Mishra-Sharma +1
A dark photon may kinetically mix with the Standard Model photon, leading to observable cosmological signatures. The mixing is resonantly enhanced when the dark photon mass matches…
Heavy Thermal Relics from Zombie Collisions
Eric David Kramer, Eric Kuflik, Noam Levi +2
We propose a new thermal freezeout mechanism which results in dark matter masses exceeding the unitarity bound by many orders of magnitude, without violating perturbative unitarity…
