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…
