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…
Preheating in Supersymmetric Theories
Z. Chacko, H. Murayama, M. Perelstein
We examine the particle production via preheating at the end of inflation in supersymmetric theories. The inflaton and matter scalars are now necessarily complex fields, and their…
