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…

Composite Dark Matter and Neutrino Masses from a Light Hidden Sector
Aqeel Ahmed, Zackaria Chacko, Niral Desai +3
We study a class of models in which the particle that constitutes dark matter arises as a composite state of a strongly coupled hidden sector. The hidden sector interacts with the…

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…
