Long-Lived-Particle Signals of a Composite Hidden Sector through the Neutrino Portal
Aqeel Ahmed, Zackaria Chacko, Niral Desai +4
We explore the signals of a scenario in which the composite states of a strongly coupled hidden sector couple to the Standard Model through the neutrino portal, giving rise to the…
Dark Matter-Dark Radiation Interactions and the Hubble Tension
Manuel A. Buen-Abad, Zackaria Chacko, Ina Flood +3
Models in which a subcomponent of dark matter interacts with dark radiation have been proposed as a solution to the Hubble tension. In this framework, the interacting subcomponent…
Searching for Hidden Sector Particles at Neutrino Telescopes
Sagar Airen, Zackaria Chacko, Can Kilic +1
We explore the possibility of directly detecting light, long-lived hidden sector particles at the IceCube neutrino telescope. Such particles frequently arise in non-minimal hidden…
General form of effective operators from hidden sectors
Aqeel Ahmed, Zackaria Chacko, Ina Flood +2
We perform a model-independent analysis of the dimension-six terms that are generated in the low energy effective theory when a hidden sector that communicates with the Standard Mo…
Atomic Dark Matter, Interacting Dark Radiation, and the Hubble Tension
Manuel A. Buen-Abad, Zackaria Chacko, Ina Flood +3
We present a new class of interacting dark sector models that can address the Hubble tension. Interacting dark radiation (DR) has previously been put forward as a solution to the p…
